dt-bindings: phy: Remove phy-stih41x-usb binding

The driver was removed in 2016 in commit fb954c48aea6 ("phy:
stih41x-usb: Remove usb phy driver and dt binding  documentation.") and
somehow the DT binding got dropped despite the subject.

-STMicroelectronics STiH41x USB PHY binding
-------------------------------------------
-
-This file contains documentation for the usb phy found in STiH415/6 SoCs from
-STMicroelectronics.
-
-Required properties:
-- compatible   : should be "st,stih416-usb-phy" or "st,stih415-usb-phy"
-- st,syscfg    : should be a phandle of the syscfg node
-- clock-names  : must contain "osc_phy"
-- clocks       : must contain an entry for each name in clock-names.
-See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-- #phy-cells   : must be 0 for this phy
-See: Documentation/devicetree/bindings/phy/phy-bindings.txt
-
-Example:
-
-usb2_phy: usb2phy@0 {
-       compatible      = "st,stih416-usb-phy";
-       #phy-cells      = <0>;
-       st,syscfg       = <&syscfg_rear>;
-       clocks          = <&clk_sysin>;
-       clock-names     = "osc_phy";
-};
