phy: stm32: sync with upstream

This imports following Linux patches by Amelie Delaunay
<amelie.delaunay@foss.st.com>:

  phy: stm32: manage 1v1 and 1v8 supplies at pll activation/deactivation
  phy: stm32: replace regulator_bulk* by multiple regulator_*
  phy: stm32: ensure pll is disabled before phys creation
  phy: stm32: ensure phy are no more active when removing the driver
  phy: stm32: rework PLL Lock detection
  ARM: dts: stm32: add usbphyc vdda1v1 and vdda1v8 supplies on stm32mp151

This makes barebox compatible to the new device tree binding,
reduces our differences to the upstream driver and removes
the power_on, power_off callbacks which are now integrated
into init/exit.

The device tree override is necessary, because unlike with Linux,
barebox regulator core doesn't descend into child nodes to enable
their regulators, but that's a fix for another day.
