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

Browse source 
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.

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
