From: Konstantin Porotchkin <kostap at marvell.com>

This series of patches adds a new PHY driver for supporting CP110 UTMI
PHY in Linux. Currently the functionality of USB ports connected to
this PHY depends on boot loader setup.
The new driver eliminates kernel configuration dependency from the boot
loader. 

v3:
- rebase on top of Linux 5.12-rc2
- convert Armada 3700 UTMI PHY DT binding document to YAML schema
- create a separate DT binding for Armada CP11x UTMI PHY in YAML format
- change UTMI PHY port node names from "phy" to "usb-phy"

v2:
- extend the comment about reference clock 
- fix driver probe function, add some prints
- move to usage of dr_mode from connected USB controller instead of
  dedicated device tree property
