sunxi: usbc: Initialize vusb value on request_resources

Browse source 
On boards which use the pmic to enable/disable vbus on the otg port, the
vbus value is not reset to 0 on reset, as reset only resets the SoC and not
the pmic, so explicitly set vbus to 0 on init (request_resources) by moving
the gpio_direction_output call into request_resources.

For consistency also move the gpio_direction_input call for vbus-detect into
request_resources.
