genirq: axxia: Fix irq_set_affinity to allow use with buslocks

commit  7c9d7ff1f780a4a729f59dc01b39296512a062cf from
https://github.com/axxia/linux-yocto.git

 axxia-linux/v5.10/standard/axxia-dev/base

Modify irq_set_affinity() to allow usage of bus locks with "slow bus" IRQ
controllers. This only affects those BSPs that use bus locks in their IRQ
controllers, such as the Intel Axxia GIC. The recommendation for this
change originated from Thomax Gleixner at Linutronix.
