This results a common ecc layout across RBL, U-boot Linux with BCH8.

Changes since v3:
- Rebased on top of omap_dt/for_3.8/dts_part2
- Add pwm backlight for am335xevm_sk
- Moved tipwmss.h to pwm-tipwmss.h

Changes since v4:
- Made dt match property in single line for consistency
- Use SIMPLE_DEV_PM_OPS

As part of PWM subsystem integration, PWM subsystem are sharing
resources like clock across submodules (ECAP, EQEP EHRPWM). To handle
resource sharing IP integration rework on parent child relation
between PWMSS and ECAP, EQEP EHRPWM child devices to support runtime PM.

EHRPWM module requires explicit clock gating of TBCLK from control
module. Hence add TBCLK clock node in clock tree for EHRPWM modules.

Changes since v4:
- Add dev_id field in clcok tree for TBCLK to remove support
Add PWMSS device tree nodes in relation with ECAP EHRPWM DT nodes to
AM33XX SoC family. Also populates device tree nodes for ECAP EHRPWM by
adding necessary properties like pwm-cells, base reg set disabled as
status.
