Hi Bence,

I agree, the mchp_tc_count_function_write() could be cleaned up and
divided into separate functions dedicated to configuring each mode
(perhaps regmap_update_bits() could be leveraged too), but that would be
a much more invasive update. For the sake of making backporting easy to
address this particular issue, I've kept the changes here localized to
just the probe() function. Once the fix is merged, someone can try
tackling a more proper refactor of the mchp_tc_count_function_write()
code.
