[PATCH 1/2] soundwire: Improve channel min/max comments

[Charles Keepax <ckeepax@opensource.cirrus.com>]

Presently, the comments for the minimum and maximum channels are
misleading. In the SDCA specification these are actually channel
indexes not a count of the number of channels. So for example
min_ch=4 and max_ch=5 means that 1 or 2 channels are supported.
Update the comments associated with the structure to make this
more clear.
