Harvey Hunt 4b2312bd05 irqchip/mips-gic: Fix IRQs in gic_dev_domain 
When allocating a new device IRQ, gic_dev_domain_alloc() correctly calls
irq_domain_set_hwirq_and_chip(), but gic_irq_domain_alloc() does not. This
means that gic_irq_domain believes all IRQs from the dev domain have an
hwirq of 0 and creates incorrect mappings in the linear_revmap. As
gic_irq_domain is a parent of the gic_dev_domain, this leads to an
inability to boot on devices with a GIC. Excerpt of the error:

[    2.297649] irq 0: nobody cared (try booting with the "irqpoll" option)
...
[    2.436963] handlers:
[    2.439492] Disabling IRQ #0

Fix this by calling irq_domain_set_hwirq_and_chip() for both the dev and
irq domain.

Now that we are modifying the parent domain, be sure to clear it up in
case of an allocation error.

Fixes: 2af70a9620 ("irqchip/mips-gic: Add a IPI hierarchy domain")
