Issue description: On some pmics, the policy enable for thermal alerts refers to different bit fields of the same registers, whereas on other pmics, the policy enable refers to the same bit field on different registers. Previous implementation did not provide the flexibility for supporting the first approach. Solution: Modified the policy enable function to take bit field as well. The use of bit field is left to the pmic specific opregion driver.
