Emmanuel Vadot 4dd8db62e9 Add IRQ resource to SPIBUS
Add capability to SPIBUS to have child device with IRQ.
For example many ADC chip have a dedicated pin to signal "data ready"
and the host can just wait for a interrupt to go out and read the result.

It is the same code as in R282674 and R282702 for IICBUS by Michal Meloun
