[PATCH] powerpc/msi: fix section mismatch warning

[Denis Kirjanov]

Building with CONFIG_DEBUG_SECTION_MISMATCH
gives the following warning:

WARNING: vmlinux.o(.text+0x41fa8): Section mismatch in reference from
the function .msi_bitmap_alloc() to the function
.init.text:.memblock_virt_alloc_try_nid()
The function .msi_bitmap_alloc() references
the function __init .memblock_virt_alloc_try_nid().
This is often because .msi_bitmap_alloc lacks a __init
annotation or the annotation of .memblock_virt_alloc_try_nid is wrong.
