xtensa: Fix section mismatch between memblock_reserve and mem_reserve

Browse source 
[ Upstream commit adefd051a6707a6ca0ebad278d3c1c05c960fc3b ]

Since commit 9012d011660ea5cf2 ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), xtensa:tinyconfig fails to build with section
mismatch errors.

WARNING: vmlinux.o(.text.unlikely+0x68): Section mismatch in reference
	from the function ___pa()
	to the function .meminit.text:memblock_reserve()
WARNING: vmlinux.o(.text.unlikely+0x74): Section mismatch in reference
	from the function mem_reserve()
	to the function .meminit.text:memblock_reserve()
FATAL: modpost: Section mismatches detected.

This was not seen prior to the above mentioned commit because mem_reserve()
was always inlined.

Mark mem_reserve(() as __init_memblock to have it reside in the same
section as memblock_reserve().
