Change RMA size from 512 MB to 768 MB which will result

Secure Boot or FADump, the 512 MB RMA memory is not sufficient for
booting. With this 512 MB RMA, GRUB2 run out of memory and unable to
load the necessary. Sometimes even usage of CDROM which requires more
memory for installation along with the options mentioned above troubles
the boot memory and result in boot failures. Increasing the RMA size
will resolves multiple out of memory issues observed in PowerPC.
