mfd: Use genirq in 88pm860x
Use genirq to simplify IRQ handling in 88pm860x. Remove the interface of mask/free IRQs on 88pm860x. All these work is taken by genirq. Update the touchscreen driver of 88pm860x since IRQ handling is changed. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>wifi-calibration
