dt-bindings: phy: mediatek: tphy: add a property for force-mode switch 



Due to some old SoCs with shared t-phy between usb3 and pcie only support
force-mode switch, and shared and non-shared t-phy may exist at the same
time on a SoC, can't use compatible to distinguish between shared and
non-shared t-phy, add a property to supported it.
Currently, only support switch from default pcie mode to usb3 mode.
But now prefer to use "mediatek,syscon-type" on new SoC as far as possible.

        description:

          The force mode is used to manually switch the shared phy mode between

          USB3 and PCIe, when USB3 phy type is selected by the consumer, and

          force-mode is set, will cause phy's power and pipe toggled and force

          phy as USB3 mode which switched from default PCIe mode. But perfer to

          use the property "mediatek,syscon-type" for newer SoCs that support it.
