soc/tegra: pmc: Restrict power-off handler to Nexus 7

The Tegra PMC power-off handler exists solely to reboot the Nexus 7 into
a special bootloader mode when a USB cable is connected, so that the
bootloader can display battery status instead of powering off. There is
no reason to register it on any other Tegra board.

Guard the registration behind of_machine_is_compatible("asus,grouper")
and rename the handler to tegra_pmc_grouper_power_off_handler to make
its scope explicit. The of_machine_is_compatible() check inside the
handler itself is now redundant and is removed.

This also avoids occupying SYS_OFF_PRIO_FIRMWARE on boards that have
other handlers at that priority level.
