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 <avinashphi...@ti.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.
