[PATCH RFC v9 10/25] memblock: Move INIT_MEMBLOCK_* macros to header

[Kevin Brodsky <kevin.brodsky@arm.com>]

The upcoming page table allocator for the kpkeys_hardened_pgtables
feature will need to know the maximum number of memblock regions.
Move the corresponding macros to <linux/memblock.h> to allow that.

INIT_MEMBLOCK_{RESERVED,MEMORY}_REGIONS may be overridden, but this
should be fine as only arm64 and loong currently do that and the
relevant header is already (indirectly) included by
<linux/memblock.h>.
