This change adds a new PCD PcdArmHdlcdSwapBlueRedSelect
to swap values for HDLCD RED_SELECT and BLUE_SELECT registers
on platforms where blue and red hardware lines are swapped.
If set to TRUE in the platform dsc, HDLCD library will swap the values
while setting RED_SELECT and BLUE_SELECT registers. The default
value of the PCD is FALSE.
NOTE: The motive for this is that a discrepancy in the Red/Blue lines
exists between some VersatileExpress platforms. Rather than have
divergent code, this build switch allows a simple, pragmatic solution.

Current HDLCD and PL111 platform libraries do not support display modes
with PixelBlueGreenRedReserved8BitPerColor format, i.e. because of
historical confusion, they do not support the UEFI default
PixelBlueGreenRedReserved8BitPerColor format
In LcdPlatformLib for PL111, LcdPlatformQueryMode returns the pixel
format as PixelRedGreenBlueReserved8BitPerColor which is wrong, because
that does not match the display controller's pixel format which is set
to BGR in PL111Lcd LcdHwLib.
Also it is not possible to configure pixel format as RGB/BGR for the
display modes for a platform at build time.
This change adds PcdGopPixelFormat to configure pixel format as
PixelRedGreenBlueReserved8BitPerColor or
PixelBlueGreenRedReserved8BitPerColor or
PixelBitMask.
With this change, pixel format can be selected in the platform specific
.dsc file for all supported display modes.
Support for PixelBitMask is not implemented in PL111 or HDLCD LcdHwLib
libraries, hence HDLCD and PL111 platform libraries will return error
EFI_UNSUPPORTED if PcdGopPixelFormat is set to PixelBitMask. Indeed,
it is not clear what selecting PixelBitMask might mean, but the option
is allowed as it might suit a custom platform.

Platforms that rely on NorFlashDxe to format the variable store (as
opposed to formatting a variable store template through an FDF file, as
part of the build) should hook NvVarStoreFormattedLib into the variable
drivers they use, so that the latter await our cue.

The lazy initialization of the varstore FVB makes no longer sense at this
point:
- "mNorFlashInstanceTemplate.Initialize" is NULL;
- in NorFlashCreateInstance(), we only set Instance->Initialize to
non-NULL -- namely NorFlashFvbInitialize() -- if the FVB stands for the
variable store (see "ContainVariableStorage" / "SupportFvb");
- we call Instance->Initialize() from three places:
- from NorFlashWriteSingleBlock(), which is too late for the variable
read service ("variable write" depends on "variable read");
- from InitializeFvAndVariableStoreHeaders(), but that is only reachable
from NorFlashFvbInitialize(), i.e. recursively from
Instance->Initialize() itself;
- and from FvbRead(), which is never called by the variable driver, only
by the FTW driver. However, the variable driver may read (not write)
the memory-mapped varstore flash chip before the FTW driver is
dispatched.
Therefore the lazy initialization is both superfluous and insufficient.
Initialize the varstore headers eagerly, before we install the FVB
protocol interface.

Instead of completely removing the memory occupied by the primary PrePi
FV from the memory map, thereby making it inaccessible to the OS, mark
it as boot services data. This will ensure that the memory is left
untouched by the firmware, but will release it to the OS when it calls
ExitBootServices().
Note that for reasons that are not entirely clear, this only works as
desired if the memory allocation HOB and the resource descriptor HOB
that describe the region are identical in offset and size, and so we
still need to iterate over the descriptors and split them up.

Commit 8ae5fc1829 ("ArmPlatformPkg/MemoryInitPeiLib: don't reserve

the primary firmware volume from the memory map. The assumption was that
this is no longer necessary now that we no longer expose compression and
PE/COFF loader library code from the PrePi module to DXE core.
However, the FV is still declared, and so code may attempt to access it
anyway, which may cause unexpected results depending on whether the
memory has been reused for other purposes in the mean time. So revert
this change in preparation of dealing with this in a better way.
