gpio: turris_omnia_mcu: Add support for system power off via sysreset
Add support for system power off via UCLASS_SYSRESET. Newer versions of
Turris Omnia MCU firmware can power off the board (MCU will disable
almost all voltage regulators and go into low power mode).
Move the MCU driver into drivers/misc and register it under UCLASS_MISC.
The sysreset and gpio device are bound as child devices of the MCU device.
