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.
