[PATCH v7 05/10] kern/ieee1275/init: ppc64: Rename regions_claim to grub_regions_claim

[Stefan Berger]

Rename regions_claim() to grub_regions_claim() to make it available for
memory allocation. The ieee1275 loader will use this function on PowerVM
and KVM on Power and thus avoid usage of memory that it is not allowed
to use.
