Some platform support dynamic clocking, which is controlled by some
jumper setting or hardware registers. Result of that is that PCD
PL011UartClkInHz would need to be updated for frequency change.
This patch implements support for dynamic frequency for PL011 uart.
This patch implements default lib, which is using Pcd. Platform which
needs dynamic clocking needs implement PL011UartClockLib

This change adds support for the ARM Mali DP500/DP500/DP650 display
processors using the GOP protocol. It has been tested on FVP base
models + DP550 support. This change adds platform independant LcdHwLib
library. A corresponding platform specific library will be submitted
to edk-platforms/Platform/ARM/VExpressPkg.
This change does not modify functionality provided by PL111 or
HDLCD. This LcdHwLib implementation should be suitable for those
platforms that implement ARM Mali DP500/DP550/DP650 replacing
PL111/HDLCD.
Only graphics layer of the ARM Mali DP is configured for rendering
the RGB/BGR format frame buffer to satisfy the UEFI GOP requirements
Other layers e.g. video layers are not configured.

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.
