[PATCH v4 0/6] Implement proper sysreset ability for Tegra SoCs and some PMICs

[Svyatoslav Ryhel]

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.
