When SaSbQemu platform is configured with multi memory nodes, like 
numa architecture, os will ignore any memory node in the device tree 
except the first one.The kernel reads UEFI memory map for memory 
information when booting via UEFI.However UEFI only allocates the 
first memory node memory space for SbsaQemu platform, in this 
scenario we can use the GCD services to add memory spaces 
for high memory node.

Changes in v2:
- get the information of memory via SMC rather than FdtClientDxe.
- add a new driver rather than use HighMemDxe.
