Clean up documentation of RCIN# open-drain workaround
On many of the Haswell boards, RCIN# was attached to PL6, which is not
an open-drain capable GPIO. As a workaround, we toggle it to an input
to get it into a high-Z state. Now that we understand the problem,
document it and remove the FIXME tag from the comments.
Baytrail systems map RCIN# to a different pin, so don't need this
workaround at all.
