As part of PWM subsystem integration, PWM subsystem are sharing
resources like clock across submodules (ECAP, EQEP & EHRPWM).
To handle resource sharing & IP integration
1. Rework on parent child relation between PWMSS and
ECAP, EQEP & EHRPWM child devices to support runtime PM.
2. Add support for opt_clks in EHRPWM HWMOD entry to handle additional
clock gating from control module.
3. Add HWMOD entries for EQEP PWM submodule.

Changes since v1:
- Remove ADDR_TYPE_RT for PWM sub module register entries.
