phylink: ReST-ify the phylink_pcs_neg_mode() kdoc

Stephen reports warnings when rendering phylink kdocs as HTML:

  include/linux/phylink.h:110: ERROR: Unexpected indentation.
  include/linux/phylink.h:111: WARNING: Block quote ends without a blank line; unexpected unindent.
  include/linux/phylink.h:614: WARNING: Inline literal start-string without end-string.
  include/linux/phylink.h:644: WARNING: Inline literal start-string without end-string.

Make phylink_pcs_neg_mode() use a proper list format to fix the first
two warnings.

The last two warnings, AFAICT, come from the use of shorthand like
phylink_mode_*(). Perhaps those should be special-cased at the Sphinx
level.
