I think either way is ok to address the warning. If we wanted to do this
properly, the mx{25,27,31,35,5}_revision functions could all be removed
and the logic hooked up to imx_set_soc_revision() in the same way that
they already use mxc_set_cpu_type() for drivers/soc/imx/soc-imx.c.

I'll leave it up to you, if you want to merge Martin's patches or
a replacement for the soc-imx driver through the imx tree for 6.5,
I'll drop my patch from this series, otherwise I'll keep it for now
and we can still do it better at later point.
