[PATCH] ARM: mark prepare_page_table as __init

From: Arnd Bergmann

From: Arnd Bergmann <arnd@xxxxxxxx>

In some configurations when building with gcc-11, prepare_page_table
does not get inline, which causes a build time warning for a section
mismatch:

WARNING: modpost: vmlinux.o(.text.unlikely+0xce8): Section mismatch in reference from the function prepare_page_table() to the (unknown reference) .init.data:(unknown)
The function prepare_page_table() references
the (unknown reference) __initdata (unknown).
This is often because prepare_page_table lacks a __initdata
annotation or the annotation of (unknown) is wrong.

Mark the function as __init to avoid the warning regardless of the
inlining.
