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.

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.
