usb: ehci-mx6: Add i.MX95 OTG support
When the usb node is defined dr_mode="otg" ehci_usb_phy_mode() is called
to determine the mode from status registers.
The IMX95RM does not currently define the USBNC STATUS register but it is
assumed to be an omission as the first three registers are defined.
It has been expirimentally verified that the USBNC_PHY_STATUS register
at offset 0x23C bit4 (USBNC_PHYSTATUS_ID_DIG) reads 0 when USB_ID is GND
and 1 when floating.
Use is_imx9() as this driver works for i.MX91, i.MX93 and i.MX95 and all
of these determine the role based on the USBNC_PHY_STATUS register.
