This series brings phy tuning to stm32-usbphyc with a new optional
device tree property st,phy-tuning, the elements of which
(st,phy-tuning node properties) are also optional.
A prior patch add resume routine, which is used to restore UTMI
switch and phy tuning configuration, as they can be reset if
deep low power state is achieved.
