bcma: gpio: Use generic_handle_irq_safe()
On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force
threaded and runs with interrupts enabled. The invocation of
generic_handle_irq() with interrupts enabled triggers a lockdep warning due
to a non-irq safe lock acquisition.
Instead of disabling interrupts on the driver level, use
generic_handle_domain_irq_safe().
