ArmPlatformPkg: New DP500/DP550/DP650 GOP driver

Browse Source 
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.
