We've earlier added support to split the register address space into TM
and SROT regions.
Split up the regmap address space into two for the remaining platforms that
have a similar register layout and make corresponding changes to the
get_temp_common() function used by these platforms.
Since tsens-common.c/init_common() currently only registers one address
space, the order is important (TM before SROT). This is OK since the code
doesn't really use the SROT functionality yet.
