always uses "phy_no". Change it for consistency.

When updating PROG_PHY_LINK_RATE to set linkrate for a phy we used a
hard-coded initial value instead of getting the current value from the
register. The assumption was that this register would not be modified, but
in fact it was partially modified in a new version of hardware. The
hard-coded value we used changed the default value of the register to a an
incorrect setting and as a result the SAS controller could not change
linkrate for the phy.
Delete hard-coded value and always read the latest value of register before
updating it.

hisi_sas_slot_task_free() attempts to dereference SSP task for non-ATA
tasks. If the task is SMP, the code may reference the wrong structure
although this may not cause any problems.
To avoid this, only access to SSP task when slot->n_elem_dif is not 0 which
indicates this is an SSP task.

To recover non-fatal errors, no full reset is required, err_handler only
clears those pending TRs/TMRs so that SCSI layer can re-issue them. In
current err_handler, TRs are directly cleared from UFS host's doorbell but
not aborted from device side. However, according to the UFSHCI JEDEC spec,
the host software shall use UTP Transfer Request List Clear Register to
clear a task from UFS host's doorbell only when a UTP Transfer Request is
expected to not be completed, e.g. when the host software receives a
“FUNCTION COMPLETE” Task Management response which means a Transfer Request
was aborted. To follow the UFSHCI JEDEC spec, in err_handler, abort one TR
before clearing it from doorbell.

We have two knobs to control flush for write booster,
fWriteBoosterBufferFlushDuringHibernate and fWriteBoosterBufferFlushEn.
Some vendors use only fWriteBoosterBufferFlushDuringHibernate because this
can reportedly cover most scenarios. Also, there have been some reports
that flush by fWriteBoosterBufferFlushEn could lead to increased power
consumption thanks to unexpected internal operations. Consequently, we need
a way to enable or disable fWriteBoosterEn operations. Add quirk to bypass
manual flush.
