Now that the tmio_mmc driver has been split into a core and a separate MFD glue, we can support SDHI natively without the need to emulate an MFD controller. This also allows to support systems with an on-SoC SDHI controller and a separate MFD with a TMIO core.

The regulator core had suspend-prepare that turns off the regulators when entering a system-wide suspend. However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.
