On PowerVM and KVM on Power use the new memory allocation function that
honors restrictions on which memory GRUB can actually use. In the request
structure indicate the request for a single memory block along with
address alignment restrictions. Request direct usage of the memory block
by setting init_region to false (prevent it from being added to GRUB's
heap). Initialize the found addr to -1, so that -1 will be returned
to the loader in case no memory could be allocated.
Report an out-of-memory error in case the initrd could not be loaded.
