regulator: tps65910: wire up sleep control configuration
This enables configuring the PMIC's sleep mode via device-tree.
A pointer indirection to sleep mode data is removed, as it simplifies
the implementation slightly. In current kernel tree, platform data
structure is not used outside MFD cell drivers.
