platform: Add firmware-agnostic irq and affinity retrieval interface
Expand platform_get_irq_optional() to also return an affinity if available,
renaming it to platform_get_irq_affinity() in the process.
platform_get_irq_optional() is preserved with its current semantics by
calling into the new helper with a NULL affinity pointer.
