soc: fsl: qe: Use generic_handle_domain_irq()

Browse Source 
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().
