Subject: [PATCH v4] ARM: davinci: da850: add EHRPWM & ECAP DT node

Add da850 EHRPWM & ECAP DT node along with pin-mux details for EHRPWM1.
Also adds OF_DEV_AUXDATA for EHRPWM & ECAP driver to use EHRPWM & ECAP
clock.

Signed-off-by: Philip Avinash <avinashphilip@...com>
---
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.
