Subject: Remove all dc_ functions as they are not needed anymore
X-Git-Tag: rel-1.7.2~76
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=efb97840151ab3cc74ff5fa196f0269f78953d7e;p=seabios.git

Remove all dc_ functions as they are not needed anymore

As we access teh DC registers via memory we do not need all
the DC-VGA-mapping functions anymore.
