Max Filippov e0c6e864d2 xtensa: call irqchip_init only when CONFIG_USE_OF is selected ...

[ Upstream commit 6489f8d0e1d93a3603d8dad8125797559e4cf2a2 ]

During boot time kernel configured with OF=y but USE_OF=n displays the
following warnings and hangs shortly after starting userspace:

------------[ cut here ]------------

---[ end trace 1e6630e1c5eda35c ]---
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.
