This adds Rockchip RK3588 AHCI binding. In order to narrow down the
allowed clocks without bloating the generic binding, the description
of Rockchip's AHCI controllers has been moved to its own file.

ata_change_queue_depth() implements different behaviors for ATA devices
managed by libsas than for those managed by libata directly.
Specifically, if a user attempts to set a device queue depth to a value
larger than 32 (ATA_MAX_QUEUE), the queue depth is capped to the maximum
and set to 32 for libsas managed devices whereas for libata managed
devices, the queue depth is unchanged and an error returned to the user.
This is due to the fact that for libsas devices, sdev->host->can_queue
may indicate the host (HBA) maximum number of commands that can be
queued rather than the device maximum queue depth.

Change ata_change_queue_depth() to provide a consistent behavior for all
devices by changing the queue depth capping code to a check that the
user provided value does not exceed the device maximum queue depth.
This check is moved before the code clearing or setting the
ATA_DFLAG_NCQ_OFF flag to ensure that this flag is not modified when an
invlaid queue depth is provided.

While at it, two other small improvements are added:
1) Use ata_ncq_supported() instead of ata_ncq_enabled() and clear the
   ATA_DFLAG_NCQ_OFF flag only and only if needed.
2) If the user provided queue depth is equal to the current queue depth,
   do not return an error as that is useless.

Overall, the behavior of ata_change_queue_depth() for libata managed
devices is unchanged. The behavior with libsas managed devices becomes
consistent with libata managed devices.

Commit 141f3d62 ("ata: libata-sata: Fix device queue depth control")
added a struct ata_device argument to ata_change_queue_depth() to
address problems with changing the queue depth of ATA devices managed
through libsas. This was due to problems with ata_scsi_find_dev() which
are now fixed with commit 7f875850 ("ata: libata-scsi: Use correct
device no in ata_find_dev()").

Undo some of the changes of commit 141f3d62: remove the added struct
ata_device aregument and use again ata_scsi_find_dev() to find the
target ATA device structure. While doing this, also make sure that
ata_scsi_find_dev() is called with ap->lock held, as it should.

libsas and libata call sites of ata_change_queue_depth() are updated to
match the modified function arguments.

The function returned zero unconditionally, so the function returning an
int is something between useless and irritating. With the goal to make
platform drivers' remove function return void, it's helpful to convert
the function accordingly. This converts several drivers to the new
.remove_new callback that was introduced to smoothen the platform driver
conversion.
