[PATCH Dovetail v2 1/2] dovetail: genirq: Add request_percpu_irq_affinity_flags()

cobalt / evl are currently using __request_percpu_irq() for setting up
OOB IRQs. In 6.19 the signature of __request_percpu_irq() has been
updated and 7.0 will remove the function entirely, so we need a
replacement.

All other variants (like the upcoming request_percpu_irq_affinity())
are missing the flags parameter which we require.

This could be backported to all supported dovetail versions. That
would allow co-kernels to switch to the new API unconditionally.
