soc/tegra: pmc: Don't register sys-off handler for multi-socket devices

The kernel does not permit a device to register multiple sys-off
handlers for non-default priority levels. Hence, for multi-socket Tegra
devices, registering the sys-off handler in the Tegra PMC driver (which
uses the low priority level) more than once fails.

The Tegra PMC sys-off handler is supported for all current generations
of the Tegra SoC, however, it is only used as a low priority handler if
everything else fails. For example, on Tegra264 the EFI reboot handler
is called to restart the device. Therefore, for multi-socket devices,
skip the registering of the sys-off handler to because this is not
critical.
