[PATCH 05/12] soc: fsl: qe: Use generic_handle_domain_irq()

[Paul Louvel <paul.louvel@bootlin.com>]

Replace the irq_find_mapping() + generic_handle_irq() pattern with
generic_handle_domain_irq(), which handles the IRQ domain lookup
internally. This is less error-prone and more idiomatic.

Remove the now-unused irq_find_mapping() call from qepic_get_irq().
