base: arch_topology: fix section mismatch build warnings

Browse source 
Commit 2ef7a2953c ("arm, arm64: factorize common cpu capacity default code")
introduced init_cpu_capacity_callback and init_cpu_capacity_notifier
which are referenced from initcall and are missing __init{,data}
annotations resulting the below section mismatch build warnings.

"WARNING: vmlinux.o(.text+0xbab790): Section mismatch in reference from
the function init_cpu_capacity_callback() to the variable .init.text:$x
The function init_cpu_capacity_callback() references the variable
__init $x. This is often because init_cpu_capacity_callback lacks a
__init annotation or the annotation of $x is wrong."

This patch fixes the above build warnings by adding the required annotations.
