V4L/DVB (12258): em28xx: fix typo in mt352 init sequence for Terratec Cinergy T XS USB

Andy walls pointed out that we were passing 0x5d to the TUNER_GO register,
instead of 0x01.  Set the register properly (note the code did still work with
the incorrect value, so this does not address a regression).

Thanks to Andy Walls for noticing the issue.
