Our probe code is always the same so let's switch to a custom test code and a custom board info array. That allows us to omit board vendor string (ASUS uses two strings that differ in case) in the board info and use case-insensitive comparison, and also do not duplicate sensor definitions for such board variants as " (WI-FI)" when sensors are identical to the base variant. Also saves a quarter of the module size by replacing big dmi_system_id structs with smaller ones.
