scsi: ufs: core: Add support to retrieve and store TX Equalization settings
Add support for UFS v5.0 JEDEC attributes qTxEQGnSettings and
wTxEQGnSettingsExt to enable persistent storage and retrieval of
optimal TX Equalization settings.
This provides a fast-path for TX Equalization by reusing previously
stored optimal settings, avoiding TX Equalization Training (EQTR)
procedures during subsequent Power Mode changes.
When no valid TX Equalization settings are found, fall back to full TX
EQTR procedures and optionally save the results for future use.
The validity of one set of TX Equalization settings is indicated by
Bit[15] in wTxEQGnSettingsExt.
