The UFS QMP v4 PHY has a largely different register set versus USB and
PCIe. Rename the register offsets to denote that the value is specific for
the UFS PCS register.

This patch corrects the SPDX License Identifier style in
header files related to PHY drivers for Qualcomm platforms.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

QMP V3 UNI PHY is a single lane USB3 PHY without support
for DisplayPort (DP).
Main difference from DP combo QMPv3 PHY is that UNI PHY
doesn't have dual RX/TX lanes and no separate DP_COM
block for configuration related to type-c or DP.
Also remove "qcom,qmp-v3-usb3-phy" compatible string which
was earlier added for sdm845 only as there wouldn't be
any user of same.
While at it, fix has_pwrdn_delay attribute for USB-DP
PHY configuration and.

New revision (v3) of QMP PHY uses different offsets
for almost all of the registers. Hence, move these
definitions to header file so that updated offsets
can be added for QMP v3.
