rockchip: rk3399: Fix enabling boot-on regulators
The new common rockchip pinctrl driver does not support explicit requests for a particular pinctrl function. As a result, the board_init() function bails out early before enabling the boot-on regulators. Fix this by simply removing the request for pwm0, pwm2 and pwm3. The generic DM code already does the necessary configuration if necessary. Reported-by: Levin Du <djw@t-chip.com.cn> Signed-of-by: Mark Kettenis <kettenis@openbsd.org>
