[0/3] irqchip: xilinx: Switch to generic domain handler

Hi,

this series is based on cascade mode patch sent by Mubin
(https://lkml.org/lkml/2020/2/11/888 - v3 series).

The first patch is just fixing error patch. The second and the third are
converting microblaze do_IRQ() to generic IRQ handler with appropriate
changes in xilinx intc driver. I have done it in two steps to be visible
how it was done.

The last patch removes concurrent_irq global variable which wasn't wired
anywhere but it stores number of concurrent IRQs handled by one call. There
is option to get it back if needed but I haven't seen it in other archs
that's why I have removed it too.

Thanks,
Michal
