commit bb4c6910c8b41623104c2e64a30615682689a54d upstream.
There is currently no way to convey the affinity of an interrupt
via irq_create_mapping(), which creates issues for devices that
expect that affinity to be managed by the kernel.
In order to sort this out, rename irq_create_mapping() to
irq_create_mapping_affinity() with an additional affinity parameter that
can be passed down to irq_domain_alloc_descs().
irq_create_mapping() is re-implemented as a wrapper around
irq_create_mapping_affinity().
No functional change.
