This is only USB PHY support. Changes to the DWC2 (OTG) and/or OHCI
(Host) are still needed to make USB on the MP1 work.
I haven't yet groked the relation between generic phy and usb phy
frameworks, but the code is a straight port from Linux and it seems to
work[1], so let's upstream it now to make collaboration easier.
[1]: clock the EHCI and power on the PHY and 20% of the time, the bus
can be enumerated completely. Still needs further debugging,
but it's unlikely that the PHY driver is at fault.

regulator: import Linux regulator_bulk API
phy: remove unused init_data parameter
phy: populate existing ->pwr member with phy-supply
phy: introduce phy_get_by_index
regulator: port over Linux stm32 PWR regulator driver
phy: port over Linux stm32 usbphyc driver
