Subject: xtensa: allow platform and variant to initialize own irq chips
From: Daniel Glockner <dg@xxxxxxxxx>
There was already a PLATFORM_NR_IRQS define, which is now accompanied
by a VARIANT_NR_IRQS. To be able to initialize these interrupts,
init_IRQ now calls variant and platform specific hooks.
