broadwell: Work around VBIOS framebuffer issue
The first 64 bytes of the framebuffer contain garbage after running
the option rom and after calling the VBE mode set with the flag to
clear the framebuffer.
Work around this issue by clearing the first 64 bytes in the framebuffer
in the broadwell graphics setup code after it executes the VBIOS.
