Re: [PATCH v2 14/18] IOMMU: fold flush-all hook into "flush one"

Having a separate flush-all hook has always been puzzling me some. We
will want to be able to force a full flush via accumulated flush flags
from the map/unmap functions. Introduce a respective new flag and fold
all flush handling to use the single remaining hook.

Note that because of the respective comments in SMMU and IPMMU-VMSA
code, I've folded the two prior hook functions into one. For SMMU-v3,
which lacks a comment towards incapable hardware, I've left both
functions in place on the assumption that selective and full flushes
will eventually want separating.
