[PATCH v4 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 PowerKVM and thus avoid usage of memory that it is not allowed to use.
