Subject: [PATCH 1/4] ARM: dts: stm32: add usbphyc vdda1v1 and vdda1v8 supplies on stm32mp151

vdda1v1 and vdda1v8 supplies are required by USB PLL. Add them in usbphyc
node.

Subject: [PATCH 4/4] ARM: dts: stm32: add #clock-cells property to usbphyc node on stm32mp151

usbphyc is a 48Mhz clock provider: the clock can be used as clock source
for USB OTG. Add #clock-cells property to usbphyc node to reflect this
capability.

Subject: [PATCH 2/4] ARM: dts: stm32: remove usbphyc ports vdda1v1-vdda1v8 on stm32mp157c-ed1

vdda1v1 and vdda1v8 supplies are required by USB PLL, not by the PHYs.
Remove them from usbphyc child phy nodes now that they are managed in
usbphyc parent node at SoC level.
