mfd: Add power off functionality to TWL
TWL family of PMICs, used in master mode, have a power off functionality. The resulting power off sequence shuts down all the SoC supplies, LDOs, etc. The sequence is described in the datasheets chapter "Power-Off Sequence". Note, that board must be wired correctly for the power off to work as expected. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
