LF-4521-02 soc: imx: Fix section mismatch build warning due to __init

Fix below section mismatch build warning:

WARNING: modpost: vmlinux.o(.text+0x6b20b8): Section mismatch in reference
from the function imx8_soc_info() to the function .init.text:imx8mq_noc_init()
The function imx8_soc_info() references
the function __init imx8mq_noc_init().
This is often because imx8_soc_info lacks a __init
annotation or the annotation of imx8mq_noc_init is wrong.
