scsi: ufs: ufs-qcom: Implement vops apply_tx_eqtr_settings()

Browse source

On some platforms, when Host Software triggers TX Equalization Training, HW
does not take TX EQTR settings programmed in PA_TxEQTRSetting, instead HW
takes TX EQTR settings from PA_TxEQG1Setting. Implement vops
apply_tx_eqtr_setting() to work around it by programming TX EQTR settings
to PA_TxEQG1Setting during TX EQTR procedure.
