core/mem_region: Create reservations of type REGION_HW_RESERVEDskiboot-5.0.3
All current users of mem_reserve are actually wanting HW_RESERVED
memory; these reservations are for memory initialised pre-skiboot.
This change marks these regions as REGION_HW_RESERVED instead of
REGION_RESERVED. We also rename mem_reserve to mem_reserve_hw to reflect
this change.
This fixes an issue where the PRD daemon cannot find reserved ranges
(eg, the homer image) that have been created by skiboot itself.
