Subject: Apply ATI NCQ horkage to ASPEED as well

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.
