From: Keerthy <j-keerthy@xxxxxx>
Patch adds hwmod entry for 4460 thermal sensor module. Thermal sensor module
is part of Control module sharing its address space and clocked via Bandgap
Functional Clock. Adding a seperate hwmod entry for thermal sensor will
enable thermal sensor driver to manage its clock cleanly using PM runtime
interfaces.
