Prabhakar Kushwaha 5c05508971 armv8/fsl-lsch3: Support 256M mem split for MC & dbg-srvr
The agreed split of the top of memory is 256M for debug server and 256M
 for MC. This patch implements the split.

 In addition, the MC mem must be 512MB aligned, so the amount of memory
 to hide must be 512MB to achieve that alignment.
