sh: mm: re-add lost __ref to ioremap_prot() to fix modpost warning

Browse source 
When __ioremap_caller() was replaced by ioremap_prot(), the __ref
annotation added in commit af1415314a ("sh: Flag __ioremap_caller()
__init_refok.") was removed, causing a modpost warning:

    WARNING: modpost: vmlinux: section mismatch in reference: ioremap_prot+0x88 (section: .text) -> ioremap_fixed (section: .init.text)

ioremap_prot() calls ioremap_fixed() (which is marked __init), but only
before mem_init_done becomes true, so this is safe.  Hence fix this by
re-adding the lost __ref.
