Instead of locking and unlocking the clock scaling lock, surround the
command queueing code with an RCU reader lock and call synchronize_rcu().
This patch prepares for removal of the clock scaling lock.

If the UFS Device WLUN is runtime suspended and is in the same power mode,
link state, and b_rpm_dev_flush_capable (BKOP or WB buffer flush etc)
state, then it can remain runtime suspended instead of being runtime
resumed and then system suspended.

The following patch has cleared the way for that to happen:

  scsi: core: pm: Only runtime resume if necessary

So amend the logic accordingly.

Note, the ufs-hisi driver uses different RPM and SPM, but it is made
explicit by a new parameter to suspend prepare.

The build only descends into drivers/scsi/ufs/ if SCSI_UFSHCD is enabled.
Hence all later config symbols should depend on SCSI_UFSHCD to prevent
asking the user about config symbols for driver code that won't be built
anyway.  Unfortunately not all symbols have that dependency.

Fix this by wrapping them all into a big if/endif block.  Remove the now
superfluous explicit dependencies on SCSI_UFSHCD from all symbols that
already had it.
