qcacmn: Register DP, HTC, HAL modules with Runtime PM module

With restructuring in HIF runtime PM module, modules are
required to register with the HIF runtime PM module. Also,
changes are done in functions of allowing and preventing
runtime PM suspend as part of restructuring.
This change registers DP, HTC and HAL internal modules
with runtime PM module and update HIF runtime PM function
calls with the restructured code of HIF runtime PM module.
