mfd: Add missing hunk to change palmas irq to clear on read
During conversion to regmap_irq this hunk was missing being moved to MFD driver to put the chip into clear on read mode. Also as slave is now set use it to determine which slave for the register call. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
