intel_iommu: Add missed reserved bit check for IEC descriptor

IEC descriptor is 128-bit invalidation descriptor, must be padded with
128-bits of 0s in the upper bytes to create a 256-bit descriptor when
the invalidation queue is configured for 256-bit descriptors (IQA_REG.DW=1).

intel_iommu: Add missed sanity check for 256-bit invalidation queue

According to VTD spec, a 256-bit descriptor will result in an invalid
descriptor error if submitted in an IQ that is setup to provide hardware
with 128-bit descriptors (IQA_REG.DW=0). Meanwhile, there are old inv desc
types (e.g. iotlb_inv_desc) that can be either 128bits or 256bits. If a
128-bit version of this descriptor is submitted into an IQ that is setup
to provide hardware with 256-bit descriptors will also result in an invalid
descriptor error.

The 2nd will be captured by the tail register update. So we only need to
focus on the 1st.

Because the reserved bit check between different types of invalidation desc
are common, so introduce a common function vtd_inv_desc_reserved_check()
to do all the checks and pass the differences as parameters.

With this change, need to replace error_report_once() call with error_report()
to catch different call sites. This isn't an issue as error_report_once()
here is mainly used to help debug guest error, but it only dumps once in
qemu life cycle and doesn't help much, we need error_report() instead.

intel_iommu: Introduce property "stale-tm" to control Transient Mapping (TM) field

VT-d spec removed Transient Mapping (TM) field from second-level page-tables
and treat the field as Reserved(0) since revision 3.2.

Changing the field as reserved(0) will break backward compatibility, so
introduce a property "stale-tm" to allow user to control the setting.

Use pc_compat_9_1 to handle the compatibility for machines before 9.2 which
allow guest to set the field. Starting from 9.2, this field is reserved(0)
by default to match spec. Of course, user can force it on command line.

This doesn't impact function of vIOMMU as there was no logic to emulate
Transient Mapping.

According to spec, invalidation descriptor type is 7bits which is
concatenation of bits[11:9] and bits[3:0] of invalidation descriptor.

Currently we only pick bits[3:0] as the invalidation type and treat
bits[11:9] as reserved zero. This is not a problem for now as bits[11:9]
is zero for all current invalidation types. But it will break if newer
type occupies bits[11:9].

Fix it by taking bits[11:9] into type and make reserved bits check accurate.

intel_iommu: Fix for IQA reg read dropped DW field

If VT-D hardware supports scalable mode, Linux will set the IQA DW field
(bit11). In qemu, the vtd_mem_write and vtd_update_iq_dw set DW field well.
However, vtd_mem_read the DW field wrong because "& VTD_IQA_QS" dropped the
value of DW.
Replace "&VTD_IQA_QS" with "& (VTD_IQA_QS | VTD_IQA_DW_MASK)" could save
the DW field.

Test patch as below:

config the "x-scalable-mode" option:
"-device intel-iommu,caching-mode=on,x-scalable-mode=on,aw-bits=48"

After Linux OS boot, check the IQA_REG DW Field by usage 1 or 2:

intel_iommu: Implement [set|unset]_iommu_device() callbacks

Implement [set|unset]_iommu_device() callbacks in Intel vIOMMU.
In set call, we take a reference of HostIOMMUDevice and store it
in hash table indexed by PCI BDF.

Note this BDF index is device's real BDF not the aliased one which
is different from the index of VTDAddressSpace. There can be multiple
assigned devices under same virtual iommu group and share same
VTDAddressSpace, but each has its own HostIOMMUDevice.
