The first patch in this series changes the IOMMU specification for
the IPA node in "sc7180.dtsi" to identify two streams distinctly,
rather than specifying them with a mask. This was inspired by
something Bjorn did recently for IPA in "sdm845.dtsi".
The second and third just replace 0 with GIC_SPI in two IPA
interrupt specifications.
(I'm sorry if I should have separated these.)

Recently we learned that Android and Windows firmware don't seem to
like using 3 as an iommu mask value for IPA. A simple fix was to
specify exactly the streams needed explicitly, rather than implying
a range with the mask. Make the same change for the SC7180 platform.

Use GIC_SPI rather than 0 in the specifiers for the two ARM GIC
interrupts used by IPA.
