This driver will support a flash FVB implementation if QEMU flash
is detected.
The driver is added to the apriori list to make sure it runs
before the EmuVariableFvbRuntimeDxe driver. If this driver detects
flash support, then it will disable the EmuVariableFvbRuntimeDxe
driver by setting PcdFlashNvStorageVariableBase64.

If QEMU flash is detected, this module will install
FirmwareVolumeBlock support for the QEMU flash device.
It will also set PCDs with the results that:
1. OvmfPkg/EmuVariableFvbRuntimeDxe will be disabled
2. MdeModulePkg variable services will read/write flash directly

If QEMU flash is supported, then the PcdFlashNvStorageVariableBase64
will be set by the flash FVB driver. If it is set to a non-zero value,
then we disable memory based variables.
In future patches we will add the flash FVB driver and
force it to run before this driver. Therefore, if QEMU flash
writing is supported, then this driver will be disabled.

In a later patch we will want to mark the flash memory as a
runtime services data memory range. This will allow a new runtime
services firmware block driver to read & write flash memory when
the OS has set up virtual memory protection.
Since this memory range will appear as runtime services data, we
need to adjust the limit when scanning for PCI window 32 down to
just below the flash device. If we don't adjust the limit, then
the algorithm in PopulateFwData will fail because it will see a
EfiGcdMemoryTypeSystemMemory memory range just below 4GB.

This is to prepare for QEMU flash support which will allow
non-volatile variables to be saved in the flash image.
Note two size changes:
* NV Varstore size increased from 0xc000 to 0xe000
* FTW work size decreased from 0x2000 to 0x1000
The reason for this change is that the fault-tolerant write
support requires that the work area fit within the block
just before the fault-tolerant write spare storage blocks.
Since QEMU flash blocks have a size of 0x1000, this means
that the maximum FTW work size is 0x1000.
v2:
* Update commit message and PcdVariableStoreSize

The 1MB image with full debug and the shell included is too
large to implement flash based non-volatile variable.
After this change, building with -D FD_SIZE_1MB will
force the smaller flash size.
The default size for RELEASE build remains at 1MB, so using
-b RELEASE on the build command line will result in a
1MB flash size. For RELEASE builds -D FD_SIZE_2MB can be
used to produce a 2MB flash image.

SVN r14770 ("OvmfPkg/PlatformPei: correctly align emulated NV storage")
made sure the emulated NV storage was allocated with correct alignment.
However, the AllocateRuntimePool() -> AllocateAlignedPages() change
flipped the memory type from EfiRuntimeServicesData to
EfiBootServicesData. This causes variable services to access freed storage
at runtime. It crashes Windows 2008 R2 early at boot, for example.
Keep the alignment, but restore the memory type to EfiRuntimeServicesData,
by calling AllocateAlignedRuntimePages().
These helper functions are implemeted and documented in
"MdePkg/Library/PeiMemoryAllocationLib/MemoryAllocationLib.c".
