pinctrl: amd: 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_domain_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().
