irqchip/mxs: Panic if ioremap or domain creation fails

Browse source

Current code will only warn and then dereference the NULL pointer or
continue, which results in a fatal NULL pointer dereference later.

If the initialization fails, the machine is unusable, so panic right
away.

[ tglx: Massaged changelog and picked the irqdomain panic from the
  	next patch]
