      544496a (ARM: imx: move irq_domain_add_legacy call into avic driver)

introduced unconditional calls to irq_find_mapping and
irq_domain_add_legacy, but it's still possible to have a .config without
CONFIG_IRQ_DOMAIN=y resulting in

While selecting CONFIG_IRQ_DOMAIN would be enough, USE_OF is the future
and implies CONFIG_IRQ_DOMAIN. So select USE_OF for ARCH_MXC and drop
other explicit selects that are superflous now.
