Currently both pirq_reg_to_linkno() and pirq_linkno_to_reg() assume consecutive PIRQ routing control registers. But this is not always the case on some platforms. Introduce a new device tree property intel,pirq-regmap to describe how the PIRQ routing register offset is mapped to the link number and adjust the irq router driver to utilize the mapping.
