Today the same interrupt mask cache (stored within struct irq_chip_generic) is shared between all the irq_chip_type instances. As there are instances where each irq_chip_type uses a distinct mask register (as it is the case for Orion SoCs), sharing a single mask cache may be incorrect. So add a distinct pointer for each irq_chip_type, which for now points to the original mask register within irq_chip_generic. So no functional changes here.
