parisc: add missing __init annotation

BugLink: https://bugs.launchpad.net/bugs/1861739
[ Upstream commit aeea5eae4fd54e94d820ed17ea3b238160be723e ]

compilation failed with:

MODPOST vmlinux.o
WARNING: vmlinux.o(.text.unlikely+0xa0c): Section mismatch in reference from the function walk_lower_bus() to the function .init.text:walk_native_bus()
The function walk_lower_bus() references
the function __init walk_native_bus().
This is often because walk_lower_bus lacks a __init
annotation or the annotation of walk_native_bus is wrong.

FATAL: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
