For this to make sense, it really needs to also rename irq_host_ops
structure, the IRQ_HOST_MAP* #defines, and the irq_*_host functions.
It also /should/ adjust the users of irq_domain to rename function
local variables and structure members. Otherwise there will be an
even worse mismatch in naming.
