We can just export only the first level irqs for thermal and let the device(bxt_wcove_thermal) driver handle the second level irqs based on thermal 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.
