Amelie Delaunay 5b1af71280 phy: stm32: rework PLL Lock detection
USBPHYC has a register per phy to control and monitor the debug interface
of the HS PHY through a digital debug access.
With this register, it is possible to know if PLL Lock input to phy is
high. That means the PLL is ready for HS operation.
Instead of using an hard-coded delay after PLL enable and PLL disable, use
this bit to ensure good operating of the HS PHY.
Also use an atomic counter (n_pll_cons) to count the actual number of PLL
consumers and get rid of stm32_usbphyc_has_one_phy_active.
The boolean active in the usbphyc_phy structure is kept, because we need to
know in remove if a phy_exit is required to properly disable the PLL.

PLL block requires to be powered with 1v1 and 1v8 supplies to catch
ENABLE signal.
Currently, supplies are managed through phy_ops .power_on/off, and PLL
activation/deactivation is managed through phy_ops .init/exit.
The sequence of phy_ops .power_on/.phy_init, .power_off/.exit is USB
drivers dependent.
To ensure a good behavior of the PLL, supplies have to be managed at PLL
activation/deactivation. That means the supplies need to be put in usbphyc
node and not in phy children nodes.
