V4L/DVB (12265): em28xx: fix tuning problem in HVR-900 (R1)

When the change was introduced in the zl10353 for the i2c gate behavior, this
broke the HVR-900 which was not behind a gate. Use a version of the zl10353
config profile that indicates the tuner is not behind such a gate.

Without this patch the first tune succeeds, but subsequent tuning attempts
will fail.

The change also renames the terratec zl10353 profile I wrote to be more
generic, since it is shared by the non-terratec device.

Thanks to Michael Krufky for providing a HVR-900 and DVB-T environment to test
with.
