Both these implementations had the logic of: gear_tx == UFS_HS_G4 => PA_INITIAL_ADAPT gear_tx != UFS_HS_G4 => PA_NO_ADAPT but now both implementations pass PA_INITIAL_ADAPT as "adapt_val" and if gear_tx is not UFS_HS_G4 that is replaced with PA_INITIAL_ADAPT. In other words, it's PA_INITIAL_ADAPT in both above cases. The result is that e.g. Qualcomm SM8150 has no longer functional UFS, so adjust the logic to match the previous implementation.
