Add "fsl,imx8mp-usb-phy" compatible string for imx8mp usb phy, which is
similar with imx8mq usb phy but with some different customizations.

Add initial support for imx8mp usb phy support, imx8mp usb has
a silimar phy as imx8mq, which has some different customizations
on clock and low power design when SoC integration.

Changes for v2:
- Add header files in alphabetical order.
- Use FIELD_PREP to get the target value to set.
- Use of_device_get_match_data() to get match data for phy ops.
