soc: fsl: fix section mismatch build warnings
We get the following warning with the driver is compiled in:
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported:
WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the
function fsl_guts_probe() to the function
.init.text:of_flat_dt_get_machine_name()
The function fsl_guts_probe() references
the function __init of_flat_dt_get_machine_name().
This is often because fsl_guts_probe lacks a __init
annotation or the annotation of of_flat_dt_get_machine_name is wrong.
This patch fixes the issue by using the normal DT/OF API rather than
the of_flat_* one.
