Subject: [PATCH v2 1/2] MIPS: Make declaration for function `memory_region_available` static

Fix non-fatal warning during compilation using W=1:

arch/mips/kernel/setup.c:158:13: warning: no previous prototype for ‘memory_region_available’ [-Wmissing-prototypes]
 bool __init memory_region_available(phys_addr_t start, phys_addr_t size)
             ^~~~~~~~~~~~~~~~~~~~~~~

v2: Prefer static declaration, clarify W=1 in commit message
