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.
