scsi: ufs: add support to limit the gear speed
Max. supported gear (for both HS and PWM modes) is negotiated between
host and device during link startup. We would switch to this max.
supported gear during UFS initialization. But on some platforms
(especially emulation platforms), this negotiated max. gear may not
work reliably. Hence this change adds options to limit the max. gear
(for both HS and PWM mode) for both directions (TX and RX).
