b33ee49ac1 phy: sun4i-usb: Rework HCI PHY (aka "pmu_unk1") handling
As Icenowy pointed out, newer manuals (starting with H6) actually
document the register block at offset 0x800 as "HCI controller and PHY
interface", also describe the bits in our "PMU_UNK1" register.
Let's put proper names to those "unknown" variables and symbols.

While we are at it, generalise the existing code by allowing a bitmap
of bits to clear and set, to cover newer SoCs: The A100 and H616 use a
different bit for the SIDDQ control.

3c0b9adb89 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.
