ARM/VExpressPkg: Allocate framebuffer using EfiReservedMemoryType
As per the UEFI specification(2.7) section 12.9, the GOP framebuffer
memory can be accessed in the pre-boot and the post boot phase (by OS)
Therefore the memory type EfiBootServicesData which may no longer exist
after ExitBootServices is incorrect for the framebuffer memory
allocation. Change EfiBootServicesData with EfiReservedMemoryType
so that allocated memory can be accessed in the post boot phase.
