Changes in v3:
- Address maintainer comments:
  - Re-add example DTS
  - Drop nodename
  - Simplify compatible
- Link to v2: https://lore.kernel.org/r/20231002-pxa1928-usb-yaml-v2-1-121a7e02d29f@skole.hr

Changes in v2:
- Add myself as maintainer
- Combine HSIC and USB bindings into one
- Drop unneeded quotes
- Remove example as it can't compile (probably because of clock
  reference)
- Link to v1: https://lore.kernel.org/r/20231001-pxa1928-usb-yaml-v1-1-9309a8c0c03f@skole.hr

-* Marvell PXA1928 USB and HSIC PHYs
-
-Required properties:
-- compatible: "marvell,pxa1928-usb-phy" or "marvell,pxa1928-hsic-phy"
-- reg: base address and length of the registers
-- clocks - A single clock. From common clock binding.
-- #phys-cells: should be 0. From common phy binding.
-- resets: reference to the reset controller
-
-Example:
-
-	usbphy: phy@...0 {
-		compatible = "marvell,pxa1928-usb-phy";
-		reg = <0x7000 0xe0>;
-		clocks = <&apmu_clocks PXA1928_CLK_USB>;
-		#phy-cells = <0>;
