Several registers defined in the PCS V3 namespace in reality belong to
the PCS_UFS V3 register space. Move them to the separate header and
rename them to explicitly mention PCS_UFS. While we are at it, correct
one register in the msm8998_usb3_pcs_tbl table to use PCS register name.

Different QMP USB PHYs might have different offset from PCS to PCS_USB
register space, but the same PCS_USB register layout. Add separate
PCS_USB region space and merge related PCS_USB definitions.

Clean up the pipe clock handling by using dev_err_probe() to handle
probe deferral and dropping the obsolete comment that claimed that the
pipe clock was optional for some other PHY types.

Each USB QMP PHY device provides just a single UFS PHY. Drop support
for handling multiple child PHYs. Use phy->init_count to check if the
PHY was initialized rather than duplicating this count.

In order to split and cleanup the single monstrous QMP PHY driver,
create blind copies of the current file. They will be used for:

- UFS
- USB
- Combo DP + USB
