xtensa: Bulk conversion to generic_handle_domain_irq()

Marc Zyngier · Marc Zyngier · commit d3c149b768fb · 2021-08-12T11:39:41.000+01:00
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().
