Tejas Upadhyay 8ffa01b524 iommu/vt-d: Add RPLS to quirk list to skip TE disabling
[ Upstream commit 0a967f5bfd ]

The VT-d spec requires (10.4.4 Global Command Register, TE
field) that:

Hardware implementations supporting DMA draining must drain
any in-flight DMA read/write requests queued within the
Root-Complex before completing the translation enable
command and reflecting the status of the command through
the TES field in the Global Status register.

Unfortunately, some integrated graphic devices fail to do
so after some kind of power state transition. As the
result, the system might stuck in iommu_disable_translati
on(), waiting for the completion of TE transition.

This adds RPLS to a quirk list for those devices and skips
TE disabling if the qurik hits.
