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.

In future, we are adding support for Gear 5 and higher. To avoiding adding more tables, like tbls_hs_g5, let's use tbls_hs_max instead of tbls_hs_g4. In addition, max_hs_gear is added to indicate the maximum supported HS Gear of each configuration, so that we can check PHY submode against it to tell if tbls_hs_max needs to be applied.

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 tables, G5 specific settings are put into .tbls_hs_max, no-G5 settings are put into .tbls_hs_not_max. Only the common parts of the two sets of PHY settings are left in the .tbls. In this case, .tbls alone is not a complete set of PHY settings, so either tbls_hs_max or tbls_hs_not_max should be applied on top of the .tbls to become a complete set of PHY settings.
