This patchset converts do_reset from mach-tegra function to a proper sysreset dm driver with saving all its previous abilities.
Additionally implement do_poweroff (since Tegra sysreset can only reset) by making sysreset drivers for the most widely used PMICs on Tegra devices. This includes sysreset cells for MAX77663, TPS80031/TPS80032, TPS65910/TPS65911 and PALMAS PMIC family.
All drivers are tested on actual hardware and confirmed to work as expected.
These patches require "Add support for PMICs used on Tegra 3 devices" patches to be merged first for proper work.
