Max Filippov 6489f8d0e1 xtensa: call irqchip_init only when CONFIG_USE_OF is selected
During boot time kernel configured with OF=y but USE_OF=n displays the
following warnings and hangs shortly after starting userspace:

Failed to request irq 0 (timer)

Fix that by calling irqchip_init only when CONFIG_USE_OF is selected and
calling legacy interrupt controller init otherwise.
