tpm: Extend common APIs to support TPM TIS I2C

Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices.

This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
the I2C support. The checksum calculation is handled in the qemu
common code.
- Added wrapper function for read and write data so that I2C code can
call it without MMIO interface.

The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.

acpi: build TPM Physical Presence interface

The TPM Physical Presence interface consists of an ACPI part, a shared
memory part, and code in the firmware. Users can send messages to the
firmware by writing a code into the shared memory through invoking the
ACPI code. When a reboot happens, the firmware looks for the code and
acts on it by sending sequences of commands to the TPM.

This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't
assume that SMIs are necessary to use. It uses a similar datastructure for
the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use
of it. I extended the shared memory data structure with an array of 256
bytes, one for each code that could be implemented. The array contains
flags describing the individual codes. This decouples the ACPI implementation
from the firmware implementation.

The underlying TCG specification is accessible from the following page.

https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/

This patch implements version 1.30.

acpi: expose TPM/PPI configuration parameters to firmware via fw_cfg

To avoid having to hard code the base address of the PPI virtual
memory device we introduce a fw_cfg file etc/tpm/config that holds the
base address of the PPI device, the version of the PPI interface and
the version of the attached TPM.

tpm: allocate/map buffer for TPM Physical Presence interface

Implement a virtual memory device for the TPM Physical Presence interface.
The memory is located at 0xFED45000 and used by ACPI to send messages to the
firmware (BIOS) and by the firmware to provide parameters for each one of
the supported codes.

This interface should be used by all TPM devices on x86 and can be
added by calling tpm_ppi_init_io().

Note: bios_linker cannot be used to allocate the PPI memory region,
since the reserved memory should stay stable across reboots, and might
be needed before the ACPI tables are installed.

OpenRISC cleanups and Fixes for QEMU 3.0

Mostly patches from Richard Henderson fixing multiple things:
* Fix singlestepping in GDB.
* Use more TB linking.
* Fixes to exit TB after updating SPRs to enable registering of state
changes.
* Significant optimizations and refactors to the TLB
* Split out disassembly from translation.
* Add qemu-or1k to qemu-binfmt-conf.sh.
* Implement signal handling for linux-user.

Then there are a few fixups from me:
* Fix delay slot detections to match hardware, this was masking a bug
in the linus kernel.
* Fix stores to the PIC mask register

Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-3.0-20180703' into staging

ppc patch queue 2018-07-03

Here's a last minue pull request before today's soft freeze. Ideally
I would have sent this earlier, but I was waiting for a couple of
extra fixes I knew were close. And the freeze crept up on me, like
always.

Most of the changes here are bugfixes in any case. There are some
cleanups as well, which have been in my staging tree for a little
while. There are a couple of truly new features (some extensions to
the sam460ex platform), but these are low risk, since they only affect
a new and not really stabilized machine type anyway.

Higlights are:
* Mac platform improvements from Mark Cave-Ayland
* Sam460ex improvements from BALATON Zoltan et al.
* XICS interrupt handler cleanups from Cédric Le Goater
* TCG improvements for atomic loads and stores from Richard
Henderson
* Assorted other bugfixes
