this version misses the entire IRQ handling we already had on linux-omap
tree, so it's quite a regression.

There's no interrupts used in plain CBUS protocol/communication I think?

But Retu MFD supports the GPIO IRQ. I added the code for this set. And
the power button driver (patch 4/4) is using this functionality:

# cat /proc/interrupts
