clk: imx6q: fix section mismatch warning [Linux 5.3]

This Linux kernel change "clk: imx6q: fix section mismatch warning" is included in the Linux 5.3 release. This change is authored by Arnd Bergmann <arnd [at] arndb.de> on Mon Jun 17 13:11:35 2019 +0200. The commit for this change in Linux stable tree is 0e12248 (patch).

clk: imx6q: fix section mismatch warning

The imx6q_obtain_fixed_clk_hw lacks an __init marker, which
leads to this otherwise harmless warning:

WARNING: vmlinux.o(.text+0x495358): Section mismatch in reference from the function imx6q_obtain_fixed_clk_hw() to the function .init.text:imx_obtain_fixed_clock_hw()
The function imx6q_obtain_fixed_clk_hw() references
the function __init imx_obtain_fixed_clock_hw().
This is often because imx6q_obtain_fixed_clk_hw lacks a __init
annotation or the annotation of imx_obtain_fixed_clock_hw is wrong.
