ARM/VExpressPkg: Reserving framebuffer at build
This change uses two PCDs, PcdArmLcdFrameBufferBase and
PcdArmLcdFrameBufferSize introduced in correspondiong EDK2 patch to
reserve framebuffer in DRAM if these values are defined in platform
specific DSC file, avoiding the need to allocate dynamically.
This allows the framebuffer to appear as "I/O memory" outside of the
normal RAM map, which is similar to the "VRAM" case.
