Subject: [PATCH] mfd: ezx-pcap: Use generic_handle_irq_safe().

References: SLE Realtime Extension
Patch-mainline: v5.18-rc1
Git-commit: 83d9b7e3955d32d3e4e3321029f655716cb21c99

Instead of manually disabling interrupts before invoking use
generic_handle_irq_safe() which can be invoked with enabled and disabled
interrupts.
