misc: tegra_cec: add DT matching entry

Auxdata still have to be provided in of_platform_populate()
during early boot device detection to get the device correctly
named as "tegra_cec".  Failing to do so will result in device
probe failure as of_device_make_bus_id() will name the device
as "[phys_base].tegra_cec" and cause clock assignment failure.
