[PATCH 3/4] ARM: shmobile: koelsch: Add DA9063 PMIC device node for system restart

[Geert Uytterhoeven <geert+renesas@glider.be>]

Add a minimal device node for the DA9063 PMIC, which is connected to i2c6.
This allows the system to be restarted when the watchdog timer times
out, or when a system restart is requested.

Regulator support is not yet included, as no DT support code nor DT
binding documentation exists for the regulator functionality.

Restart by watchdog timeout is working now.
Manual system restart depends on "[PATCH 1/4] watchdog: da9063: Add restart
handler support".
