Subject: [PATCH] [HALX64] Do not claim to handle display reset if you don't.
 Fix bootvid display initialization in x64 as a result.

The HalpBiosDisplayReset() function is currently stub-plemented.
Returning FALSE will make bootvid take the route of fully
re-initializing the VGA display all by itself.
