    misc: microchip: pci1xxxx: Fix Kernel panic during IRQ handler registration

    Resolve kernel panic while accessing IRQ handler associated with the
    generated IRQ. This is done by acquiring the spinlock and storing the
    current interrupt state before handling the interrupt request using
    generic_handle_irq.

    A previous fix patch was submitted where ‘generic_handle_irq’ was
    replaced with ‘handle_nested_irq’. However, this change also causes
    the kernel panic where after determining which GPIO triggered the
    interrupt and attempting to call handle_nested_irq with the mapped
    IRQ number, leads to a failure in locating the registered handler.
