ARM: dts: ti: Add specific compatibles for SCM conf nodes

Browse Source 
writing-bindings.rst rules dictate that "syscon" must come with a
specific compatible identifying the register layout.  Add specific
compatibles for these devices.

This also allows to solve a different problem: "syscon" is contradictory
to "simple-bus".  A system controller with registers having their own
functions is not really a trivial MMIO simple bus.  These two cannot be
used together, unless listed as an exception.
