V4L/DVB (12156): em28xx: Fix tuning for Terratec Cinergy T XS USB (zl10353 version)
Fix the code so that the zl10353 version of the Terratec Cinergy T XS USB starts working again. This includes fixing what must have been a typo in the GPIO definition for the digital side of the board, and setting of the disable_i2c_gate_ctrl property for the zl10353 config, so that the i2c bus doesn't get wedged the first time something tries to close the gate. Also, add a printk() making clear that the mt352 version still isn't supported. This issue is still being actively debugged, but in the meantime at least the dmesg output will show a very clear error... Thanks to Jelle de Jong for providing sample hardware to test with. Thanks to Simon Kenyon for testing various patches and providing SSH access to his environment so I could debug with access to a valid signal source.
