[POWERPC] fsl_soc: Fix get_immrbase() to use ranges, rather than reg.
Don't depend on the reg property as a way to determine the base of the immr space. The reg property might be defined differently for different SoC families. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
