__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

We faced a problem with passing through a PCI device with 64GB BAR to UEFI
guest. The BAR is expectedly programmed into 64-bit PCI aperture at 64G
address which pushes physical address space to 37 bits. That is above
36-bit width that OVMF exposes currently to a guest without tweaking
PcdPciMmio64Size knob.
The reverse calculation using this knob was inhereted from QEMU-KVM
platform code where it serves the purpose of finding max accessible
physical address without necessary trusting emulated CPUID physbits value
(that could be different from host physbits). On Xen we expect to use
CPUID policy to level the data correctly to prevent situations with guest
physbits > host physbits e.g. across migrations.
The next aspect raising concern - resource consumption for DXE IPL page
tables and time required to map the whole address space in case of using
CPUID bits directly. That could be mitigated by enabling support for 1G
pages in DXE IPL configuration. 1G pages are available on most CPUs
produced in the last 10 years and those without don't have many phys bits.
Remove all the redundant code now (including PcdPciMmio64.. handling
that's not used on Xen anyway) and grab physbits directly from CPUID that
should be what baremetal UEFI systems do.

When running as a Xen PVH guest, there is no CMOS to read the memory
size from. Rework GetSystemMemorySize(Below|Above)4gb() so they can
work without CMOS by reading the e820 table.
Rework XenPublishRamRegions to also care for the reserved and ACPI
entry in the e820 table. The region that was added by InitializeXen()
isn't needed as that same entry is in the e820 table provided by
hvmloader.
MTRR settings aren't modified anymore, on HVM it's already done by
hvmloader, on PVH it is supposed to have sane default. MTRR will need
to be done properly but keeping what's already been done by programs
that have run before OVMF will do for now.

Introduce XenPlatformPei, a copy of OvmfPkg/PlatformPei without some
of QEMU specific initialization, Xen does not support QemuFwCfg.
This new module will be adjusted to accommodate Xen PVH.
fw_cfg dependents that have been removed, which are dynamically skipped
when running PlatformPei on Xen:
- GetFirstNonAddress(): controlling the 64-bit PCI MMIO aperture via the
(experimental) "opt/ovmf/X-PciMmio64Mb" file
- GetFirstNonAddress(): honoring the hotplug DIMM area
("etc/reserved-memory-end") in the placement of the 64-bit PCI MMIO
aperture
- NoexecDxeInitialization() is removed, so PcdPropertiesTableEnable and
PcdSetNxForStack are left constant FALSE (not set dynamically from
fw_cfg "opt/ovmf/PcdXxxx")
- MaxCpuCountInitialization(), PublishPeiMemory(): the max CPU count is
not taken from the QemuFwCfgItemSmpCpuCount fw_cfg key;
PcdCpuMaxLogicalProcessorNumber is used intact and
PcdCpuApInitTimeOutInMicroSeconds is never changed or used.
- InitializeXenPlatform(), S3Verification(): S3 is assumed disabled (not
consulting "etc/system-states" via QemuFwCfgS3Enabled()).
- InstallFeatureControlCallback(): the feature control MSR is not set
from "etc/msr_feature_control"
(also removed FeatureControl.c as there is nothing been executed)
Also removed:
- SMRAM/TSEG-related low mem size adjusting (PcdSmmSmramRequire is
assumed FALSE) in PublishPeiMemory(),
- QemuInitializeRam() entirely,
Xen related changes:
- Have removed the module variable mXen, as it should be always true.
- Have the platform PEI initialization fails if Xen has not been
detected.
