A bunch of cleanups from various people.
- Improved GT64120 on big-endian hosts - GT64120 north bridge and MC146818 RTC devices are now target independent - Bonito64 north bridge converted to 3-phase reset API - PCI refactors around PIIX devices - Support for nanoMIPS in bootloader generator API - New YAMON Malta Avocado test - Removal of 'trap and emulate' KVM support - System-specific QMP commands restricted to system emulation

hw/intc/arm_gicv3_cpuif: Support vLPIs
The CPU interface changes to support vLPIs are fairly minor: in the parts of the code that currently look at the list registers to determine the highest priority pending virtual interrupt, we must also look at the highest priority pending vLPI. To do this we change hppvi_index() to check the vLPI and return a special-case value if that is the right virtual interrupt to take. The callsites (which handle HPPIR and IAR registers and the "raise vIRQ and vFIQ lines" code) then have to handle this special-case value.
This commit includes two interfaces with the as-yet-unwritten redistributor code: * the new GICv3CPUState::hppvlpi will be set by the redistributor (in the same way as the existing hpplpi does for physical LPIs) * when the CPU interface acknowledges a vLPI it needs to set it to non-pending; the new gicv3_redist_vlpi_pending() function (which matches the existing gicv3_redist_lpi_pending() used for physical LPIs) is a stub that will be filled in later

hw/intc/arm_gicv3_cpuif: Split "update vIRQ/vFIQ" from gicv3_cpuif_virt_update()
The function gicv3_cpuif_virt_update() currently sets all of vIRQ, vFIQ and the maintenance interrupt. This implies that it has to be used quite carefully -- as the comment notes, setting the maintenance interrupt will typically cause the GIC code to be re-entered recursively. For handling vLPIs, we need the redistributor to be able to tell the cpuif to update the vIRQ and vFIQ lines when the highest priority pending vLPI changes. Since that change can't cause the maintenance interrupt state to change, we can pull the "update vIRQ/vFIQ" parts of gicv3_cpuif_virt_update() out into a separate function, which the redistributor can then call without having to worry about the reentrancy issue.

hw/intc/arm_gicv3_its: Implement INV command properly
We were previously implementing INV (like INVALL) to just blow away cached highest-priority-pending-LPI information on all connected redistributors. For GICv4.0, this isn't going to be sufficient, because the LPI we are invalidating cached information for might be either physical or virtual, and the required action is different for those two cases. So we need to do the full process of looking up the ITE from the devid and eventid. This also means we can do the error checks that the spec lists for this command.
Split out INV handling into a process_inv() function like our other command-processing functions. For the moment, stick to handling only physical LPIs; we will add the vLPI parts later.

hw/intc/arm_gicv3_its: Implement VSYNC
The VSYNC command forces the ITS to synchronize all outstanding ITS operations for the specified vPEID, so that subsequent writes to GITS_TRANSLATER honour them. The QEMU implementation is always in sync, so for us this is a nop, like the existing SYNC command.

hw/intc/arm_gicv3_its: Implement VMOVP
Implement the GICv4 VMOVP command, which updates an entry in the vPE table to change its rdbase field. This command is unique in the ITS command set because its effects must be propagated to all the other ITSes connected to the same GIC as the ITS which executes the VMOVP command.
The GICv4 spec allows two implementation choices for handling the propagation to other ITSes: * If GITS_TYPER.VMOVP is 1, the guest only needs to issue the command on one ITS, and the implementation handles the propagation to all ITSes * If GITS_TYPER.VMOVP is 0, the guest must issue the command on every ITS, and arrange for the ITSes to synchronize the updates with each other by setting ITSList and Sequence Number fields in the command packets
We choose the GITS_TYPER.VMOVP = 1 approach, and synchronously execute the update on every ITS.
For GICv4.1 this command has extra fields in the command packet and additional behaviour. We define the 4.1-only fields with the FIELD macro, but only implement the GICv4.0 version of the command.
Note that we don't update the reported GITS_TYPER value here; we'll do that later in a commit which updates all the reported feature bit and ID register values for GICv4.

hw/intc/arm_gicv3_its: Handle virtual interrupts in process_its_cmd()
For GICv4, interrupt table entries read by process_its_cmd() may indicate virtual LPIs which are to be directly injected into a VM. Implement the ITS side of the code for handling this. This is similar to the existing handling of physical LPIs, but instead of looking up a collection ID in a collection table, we look up a vPEID in a vPE table. As with the physical LPIs, we leave the rest of the work to code in the redistributor device.
The redistributor half will be implemented in a later commit; for now we just provide a stub function which does nothing.

Implement the GICv4 VMAPI and VMAPTI commands. These write an interrupt translation table entry that maps (DeviceID,EventID) to (vPEID,vINTID,doorbell). The only difference between VMAPI and VMAPTI is that VMAPI assumes vINTID == EventID rather than both being specified in the command packet.
(This code won't be reachable until we allow the GIC version to be set to 4. Support for reading this new virtual-interrupt DTE and handling it correctly will be implemented in a later commit.)
