On omap4, we are missing several ti,hwmods properties and IO
ranges for system control modules. These are needed by the SoC
interconnect code.
Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.
In order to add these, we need to move omap4_pmx_wkup to be a
child of omap4_padconf_wkup.
On omap4 there are separate modules for control module and
control module pads. For control module core, we have this
already configured except for the missing ti,hwmods and reg
entries.
