la8: Add support for the ChronoVu LA16.

The ChronoVu LA16 is a new logic analyzer from ChronoVu with some
differences in features compared to the LA8, e.g.

 - Supports 16 channels (instead of 8).
 - Max. 200MHz samplerate (instead of 100MHz).
 - Supports state triggering (low and high channel value) and edge triggering
   (rising or falling edge), the LA8 only supports state triggering.

This driver now supports both the LA8 and LA16, but it needed a few
changes:

 - Add support for detecting multiple device instances at all.
 - Add support for both LA8 and/or LA16 devices being detected.
 - Add a device profile struct for LA8-/LA16-specific device properties.
 - Move the samplerates list to devc (it's different for LA8 and LA16).
 - Split scan() into two functions, one for scanning, one for adding a device.
 - Expand some variables and fields from uint8_t to uint16_t in order to
   support 16 channels.
 - Update the samplerate related functions to support the LA16's 200MHz.

 - Various error handling improvements and simplifications.
