[PATCH edk2-platforms v3 12/17] ARM/VExpressPkg: Allocate framebuffer using EfiRuntimeServicesData

[Girish Pathak <girish.pathak@arm.com>]

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 is incorrect for
the framebuffer memory allocation. Change EfiBootServicesData with
EfiRuntimeServicesData flag so that allocated memory can be access
by the OS in the post boot phase.
