arch_topology: Fix section miss match warning due to free_raw_capacity()

Remove the __init annotation from free_raw_capacity() to avoid
the following warning.

The function init_cpu_capacity_callback() references the
function __init free_raw_capacity().
WARNING: vmlinux.o(.text+0x425cc0): Section mismatch in reference
from the function init_cpu_capacity_callback() to the function
.init.text:free_raw_capacity().
