sunxi: usb: convert PHY GPIO functions to DM

The Allwinner USB PHY driver is still using the legacy GPIO interface,
which is now implemented by the DM_GPIO compat functions.
Those seem to have some design flaws, as setting the direction, then
later setting the value will not work, if the DM_GPIO driver is
implementing set_flags.

Fix this by using the dm_ version of the direct GPIO interface, which
uses struct gpio_desc structs to handle requested GPIOs, and actually
keeps the flags we set earlier.

This fixes USB operation on boards which need to toggle the VBUS supply
via a GPIO, like the Teres-I laptop or the BananaPi M2 Berry board.
