[v5] ARM: davinci: da850: add EHRPWM & ECAP DT node

Commit Message

Add da850 EHRPWM & ECAP DT node along with pin-mux details.
Also adds OF_DEV_AUXDATA for EHRPWM & ECAP driver to use EHRPWM & ECAP
clock.

Changes since v4:
	- Add pin mux for PWM devices ECAP & EHRPWM.

Changes since v3:
	- add pin mux info for EHRPWM1.

Changes since v1:
	- Reusing ti,am33xx<ecap/ehrpwm> as compatible field as both IP's are
	  similar with am33xx platform and da850 has no platform specific
	  dependency.

Looks good to me. Will try and see if this can make it to v3.10.

Thanks,
