genirq: Generic chip: Add linear irq domain support
Provide infrastructure for irq chip implementations which work on
linear irq domains.
- Interface to allocate multiple generic chips which are associated to
the irq domain.
- Interface to get the generic chip pointer for a particular hardware
interrupt in the domain.
- irq domain mapping function to install the chip for a particular
interrupt.
Note: This lacks a removal function for now.
