The driver shouldn't be relying on irq_base at all, it should use
regmap_get_virq() to look up the interrupt number.  If it relies on
irq_base then the user is forced to assign one (or rely on automatic
assignment, which is a bit erratic.  Otherwise it can use a linear
domain which doesn't rely on being able to allocate a big block of
interrupt numbers.
