irqchip/ls-extirq: Convert to a platform driver to make it work again

Starting with the blamed commit, the ls-extirq driver stopped working. This
is because ls-extirq, being one of the interrupt-map property abusers, does
not pass the DT checks added by the referenced commit, making it unable to
determine its interrupt parent:

  irq-ls-extirq: Cannot find parent domain
  OF: of_irq_init: Failed to init /soc/syscon@1f70000/interrupt-controller@14
      		   ((____ptrval____)), parent 0000000000000000

Instead of reverting the referenced commit, convert the ls-extirq to a
platform driver to avoid the irqchip_init() -> of_irq_init() code path
completely.

As part of the conversion, use the managed resources APIs and
dev_err_probe() so that there is no need for a .remove() callback or for
complicated error handling.
