msm: socinfo: Fix section mismatch

WARNING: vmlinux.o(.text+0x20a48): Section mismatch in reference
from the function setup_dummy_socinfo() to the function
.init.text:of_flat_dt_is_compatible() The function
setup_dummy_socinfo() references the function __init
of_flat_dt_is_compatible().  This is often because
setup_dummy_socinfo lacks a __init annotation or the annotation
of of_flat_dt_is_compatible is wrong.
