We can just export only the first level GPIO irq(BXTWC_GPIO_LVL1_IRQ) as an irq resource and let the GPIO device driver(bxt_wcove_gpio) handle the GPIO sub domain irqs based on status value of GPIO level2 interrupt status register. Also, just using only the first level irq will eliminate the bug involved in requesting only the second level irq and not explicitly enable the first level irq.
