irqdomain: Introduce irq_domain_instantiate()
The existing irq_domain_add_*() functions used to instantiate an IRQ
domain are wrappers built on top of __irq_domain_add() and describe the
domain properties using a bunch of parameters.
Adding more parameters and wrappers to hide new parameters in the
existing code lead to more and more code without any relevant value and
without any flexibility.
Introduce irq_domain_instantiate() where the interrupt domain properties
are given using a irq_domain_info structure instead of the bunch of
parameters to allow flexibility and easy evolution.
irq_domain_instantiate() performs the same operation as the one done by
__irq_domain_add(). For compatibility reason with existing code, keep
__irq_domain_add() but convert it to irq_domain_instantiate().
