This was already disabled a while ago because it caused I/O errors,
and it's severly getting into the way of the discard / write zeroes
rework.

The WRITE SAME to TRIM translation rewrites the DATA OUT buffer. While
the SCSI code accomodates for this by passing a read-writable buffer
userspace applications don't cater for this behavior. In fact it can
be used to rewrite e.g. a readonly file through mmap and should be
considered as a security fix.

This SATA controller is quite similar to the one present on the DA850
SoC, but the PHY configuration is different and it supports two HBA
ports.
The IP suffers from the same PMP issue the DA850 does - if we enable
PMP but don't use it - softreset fails. Appropriate workaround was
implemented in this driver as well.

This driver is orphan since commit b2026f708e ("ARM: at91: remove
at91sam9260/at91sam9g20 legacy board support"). Given that nobody cared
adding DT support to it, it probably means it's no longer used and is
thus a good candidate for removal.

ata_sff_qc_issue() expects upper layers to never issue commands on a
command protocol that it doesn't implement. While the assumption
holds fine with the usual IO path, nothing filters based on the
command protocol in the passthrough path (which was added later),
allowing the warning to be tripped with a passthrough command with the
right (well, wrong) protocol.
Failing with AC_ERR_SYSTEM is the right thing to do anyway. Remove
the unnecessary WARN.

Without this patch, failed probe would not free resources like irq.
ata port tdev object currently hold a reference to the ata port
object. Therefore the ata port object release function will not get
called until the ata_tport_release is called. But that would never
happen, releasing the last reference of ata port dev is done by
scsi_host_release, which is called by ata_host_release when the ata
port object is released.
The ata device objects actually do not need to explicitly hold a
reference to their real counterpart, given the transport objects are
the children of these objects and device_add() is call for each child.
We know the parent will not be deleted until we call the child's
device_del().
