[PATCH v5 1/3] pwm: rockchip: Allow polarity invert on rk3288

The rk3288 has the ability to invert the polarity of the PWM.  Let's
enable that ability.  Note that this increases pwm_cells to 3 for
rk3288.

Changes in v5: None
Changes in v4:
- Updated comment not to add caveats about pwm_cells 3.
- rockchip_pwm_set_polarity() is now static.
- Separate pwm_ops for v1 and v2; no set_polarity() in v1.
- Added a blank line.

Changes in v3:
- Don't store a private copy of polarity.
- Use true instead of 1.
- Cleanup init order with "has_invert".
