Apply ATI NCQ horkage to ASPEED as well

[Patrick McLean]

We have some machines with ASPEED SATA controllers, and are seeing the same NCQ
issues that ATI controllers (I am not sure if it's a rebranded ATI controller,
or they both have some faulty implementation). This NCQ breakage is consistent
across a few different types of drives.

Instead of maintaining a list of drives that are broken with ASPEED controllers
as well as AIT, let's just treat ASPEED controllers like ATI ones, and disable
NCQ on drives that have ATA_HORKAGE_NO_NCQ_ON_ATI set on them.

To do this first, we have to make move the definition of the ASPEED vendor from
the ast drm driver to the PCI subsystem.

[PATCH 1/2] gpu: Move ASPEED vendor ID definition to pci_ids.h

[Patrick McLean]

Currently the ASPEED PCI vendor ID is defined in drivers/gpu/drm/ast/ast_drv.c,
move that to include/linux/pci_ids.h with all the rest of the PCI vendor ID
definitions. Rename the definition to follow the format that the other
definitions follow.

or they both have some faulty implementation). This NCQ breakage is consistent

We have been running this patch on several machines for over a week now without
reproducing an issue that was happening almost daily before.

Are these ASPEED controllers all the same or a wide variety?
Quirking all controllers from the same vendor seems like an overly
broad approach to me.

Indeed. If you checked only one adapter model from ASPEED, then all that is
needed is define it with "board_ahci_noncq" in drivers/ata/ahci.c (see
ahci_pci_tbl array). NCQ support will be turned off for that particular adapter
with that.

   Please align the start of this line with the start of the above
line, so that it doesn't needlessly blend with the below line.

   The vendor IDs in this file are sorted numerically, not

This looks like a random placement.  Please keep sorted by numeric
vendor ID.  I'll make the comment at the top a little more specific.

Oh, at the same time, would you mind rewrapping at least this commit
log so it fits in 75 columns to "git log" doesn't overflow an 80
column terminal?
