The X1E80100 has three copies of an USB/DP compbo PHY, add support for this
to the Qualcomm QMP PHY driver.

this is used to be compatible with old SoCs, such as mt8195, which shares
t-phy between usb3 and pcie controller, usually, it's default mode is pcie
rc mode, and could use force mode to switch into usb3 mode, because pericfg
layer doesn't provide mode switch, also no efuse or jumper can be used;
Currently, only support switch from default pcie mode to usb3;
Note: don't use this way on new SoCs, use pericfg layer's mode switch
instead (by perperty "mediatek,syscon-type").

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 registers, which are being touched in current SM8550 UFS PHY settings,
and the values being programmed are mainly the ones working for HS-G4 mode,
meanwhile, there are also a few ones somehow taken from HS-G5 PHY settings.
However, even consider HS-G4 mode only, some of them are incorrect and some
are missing. Rectify the HS-G4 PHY settings by strictly aligning with the
SM8550 UFS PHY Hardware Programming Guide suggested HS-G4 PHY settings.

Change the last "depends on GENERIC_PHY" to use select, like the
other 170+ Kconfig users do. This can help prevent circular
