Using bool on struct is not recommended, as it wastes lots of
space. So, instead, let's use bits.
While here, convert the comments to kernel-doc format.

The T230C v2 hardware needs a mode of the si2168 chip to be
set for which the si2168 driver previously had no support.
This patch uses a specific measure to configure this on the
T230C v2 hardware only - see the flag passed via the ts_mode
attribute and its dependency on USB_PID_MYGICA_T230C2.

Some tuners produce inverted spectrum, but the si2168 is not
currently set up to accept it. This adds an optional parameter
to set the frontend up to receive inverted spectrum.
Parameter is optional and only boards who enable inversion
will utilize this.

Includes a function to set TS MODE property os si2168. The function
either disables the TS output bus, or sets mode to config option.
When going to sleep the TS bus is turned off, this makes the driver
compatible with multiple frontend usage.

Add a parameter in si2168_config to support gapped clock. This might be
necessary on some devices with higher bitrates.

Luis Alves submitted a TS mode patch to si2168 earlier, but the
patch was rejected due to a small issue. Here is a working version.
Also, setting of TS mode is moved from si2168_set_frontend to
si2168_init.
This patch adds the TS mode as a config option for the si2168 demod:
- ts_mode added to config struct.
- Possible (interesting) values are
* Parallel mode = 0x06
* Serial mode = 0x03
Currently the modules using this demod only use parallel mode.
Patches for these modules later in this patch series.
