[PATCH 4/4] arm64: tegra: smaug: mark MAX77620 as system power controller

Register the MAX77620 PMIC as the system power controller on
Pixel C so the driver can install its sys-off handler.

This allows the PMIC poweroff sequence to override the non-working
PSCI SYSTEM_OFF implementation on this platform.
