Save and restore F15TN graphics command register

In the AGESA routine GfxInitSview() called in the S3save path,
the IO Space bit was getting cleared from the command register.
This kept seabios from initializing the video bios.  If the vbios
was loaded by coreboot, this routine was skipped, allowing seabios
to initialize vbios as well.  I have modified the routine to save
and restore the command register instead of clearing the IO Space
