    irq_domain: Standardise legacy/linear domain selection

    broonie committed with Grant Likely Jul 5, 2012
    A large proportion of interrupt controllers that support legacy mappings
    do so because non-DT systems need to use fixed IRQ numbers when registering
    devices via buses but can otherwise use a linear mapping. The interrupt
    controller itself typically is not affected by the mapping used and best
    practice is to use a linear mapping where possible so drivers frequently
    select at runtime depending on if a legacy range has been allocated to
    Standardise this behaviour by providing irq_domain_register_simple() which
    will allocate a linear mapping unless a positive first_irq is provided in
    which case it will fall back to a legacy mapping. This helps make best
    practice for irq_domain adoption clearer.
