avutil/csp: Fix bogus doxy filename

Separate the blocks to make the grouping easier to grasp,
add the file properly to the group and fix the file description
incorrectly used as filename, fixing the following doxy warning:

  warning: the name 'Colorspace' supplied as the argument in
  the \file statement is not an input file
