dt-bindings: phy: imx8mq-usb: add imx95 tuning support 



The parameter value of below 3 properties are USB PHY specific. i.MX8MP
and i.MX95 USB PHY has different meanings. This will enlarge parameters
value and add constraints for them.

 - fsl,phy-tx-vref-tune-percent
 - fsl,phy-tx-rise-tune-percent
 - fsl,phy-comp-dis-tune-percent
