dt-bindings: phy: samsung,usb3-drd-phy: add exynos2200 support 



Document support for Exynos2200. As the USBDRD 3.2 4nm controller
consists of Synopsys eUSB2.0 phy and USBDP/SS combophy, which will
be handled by external drivers, define only the bus clocked used
by the link controller.

      At least two clocks::

      Typically two clocks:

        - Main PHY clock (same as USB DRD controller i.e. DWC3 IP clock), used

          for register access.

        - PHY reference clock (usually crystal clock), used for PHY operations,

          associated by phy name. It is used to determine bit values for clock

          settings register.  For Exynos5420 this is given as 'sclk_usbphy30'

          in the CMU.

          in the CMU. It's not needed for Exynos2200.
