The grub_zalloc() allocates memory for port. If the allocation for
port->name fails the function returns NULL without freeing the
previously allocated port memory. This results in a memory leak.
To avoid this we must free port before return.

Change RMA size from 512 MB to 768 MB which will result in more memory
at boot time for PowerPC. When vTPM, Secure Boot or FADump are enabled
on PowerPC the 512 MB RMA memory is not sufficient for boot. With this
512 MB RMA, GRUB runs out of memory and fails to boot the machine.
Sometimes even usage of CDROM requires more memory for installation and
along with the options mentioned above exhausts the boot memory which
results in boot failures. Increasing the RMA size will resolves multiple
out of memory issues observed on PowerPC machines.

This patch adds support for Radix, Xive and Radix_gtse in Options
vector5 which is required for KVM LPARs. KVM LPARs ONLY support
Radix and not the Hash. Not enabling Radix on any PowerVM KVM LPARs
will result in boot failure.
