techpack/dataipa: affine ipa irqs to little CPUs

Browse Source 
Some of the ipa irqs are run on CPU0 only and a few are run on CPU4.
Instead of utilizing the prime or gold clusters, affine these
completely to little cluster.
Little cluster can easily handle these interrupts and manage them
in a power efficient manner rather than handing these to the gold
clusters.
