Subject: [PATCH v2 2/2] ARM: dts: rockchip: enable pwm3 as pwm regulator for rk3066a based boards
Rayeager/Bqcurie2/Marsboard use pwm3 modulate the vdd_logic voltage,
so enable it.
Signed-off-by: Andy Yan <andy.yan@...k-chips.com>

Changes in v2:
- also enable the pwm regulator for bqcurie2 and Marsboard
