ARM: dts: msm: Clean up SMMU interrupts on 8996

We're currently registering for some interrupts that don't exist, and
we're not registering for some interrupts that we should be.  This
results in error messages like:

    d80000.arm,smmu-jpeg: found 4 context interrupt(s) but have \
        3 context banks. assuming 3 context interrupts.
    b40000.arm,smmu-kgsl: found 4 context interrupt(s) but have \
        2 context banks. assuming 2 context interrupts.

This could also result in us missing some interrupts.

Clean all of these up based on the interrupt information from the
hardware docs.
