Rob Herring eef24afb28 irq: Fix check for already initialized irq_domain in irq_domain_add 
The sanity check in irq_domain_add() tests desc->irq_data != NULL or
irq_data->domain != NULL. This prevents adding an irq_domain to a irq
descriptor when irq_data exists, which true when the irq descriptor
exists.

This went unnoticed so far as the simple domain code did not enter
this code path because domain->nr_irqs is always 0 for the simple domains.

Split the check for irq_data == NULL out and have a separate warning
for it.

[ tglx: Made the check for irq_data == NULL separate ]
