[PATCH] MdeModulePkg/EsrtDxe: allocate ESRT table from RtServicesData memory

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

Given that the firmware itself may access the ESRT table when the OS
invokes the UpdateCapsule () boot service, it requires a virtual mapping
and so it needs to be allocated from RtServicesData memory.
