[PATCH v2 0/2] arm-smmu: add master mask

[Thommy Jakobsson]

This patchset makes it possible to manually set a mask for a master.
Default behaviour when not specifying a mask is to keep current behaviour.
If masks are specified for a master, all of its stream IDs needs to have a
mask.

Platforms with a large number of IDs per master starts to show up. Its
impractical to specify all available IDs in some cases. Specific example
is the ZynqMPSoC, where the streamid have 6 bits from the AXI ID. So 2^6
IDs for each PL port, which there are 6 of.
