mfd: Add irq support in 88pm860x
88PM860x is a complex PMIC device. It contains touch, charger, sound, rtc, backlight, led, and so on. Host communicates to 88PM860x by I2C bus. Use thread irq to support this usage case. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
