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.

On SM8550, two sets of UFS PHY settings are provided, one set is to support
HS-G5, another set is to support HS-G4 and lower gears. The two sets of PHY
settings are programming different values to different registers, mixing
the two sets and/or overwriting one set with another set is definitely not
blessed by UFS PHY designers.
To add HS-G5 support for SM8550, split the two sets of PHY settings into
their dedicated overlay tables, only the common parts of the two sets of
PHY settings are left in the .tbls.
Consider we are going to add even higher gear support in future, to avoid
adding more tables with different names, rename the .tbls_hs_g4 and make it
an array, a size of 2 is enough as of now.
In this case, .tbls alone is not a complete set of PHY settings, so either
tbls_hs_overlay[0] or tbls_hs_overlay[1] must be applied on top of the
.tbls to become a complete set of PHY settings.
