mb/asrock/h77pro4-m: Use VBT provided by Linux' debugfs
The current VBT causes problems with Windows 10. Once the Intel driver
is used instead of the generic graphics driver, the display turns off
although the system keeps running normally. Linux has no issues. It had
been extracted from the vendor video BIOS, which in turn had been
extracted from the vendor firmware.
This change replaces the VBT with one that was dumped through debugfs
and the drm/i915 driver in Linux, booted from the vendor firmware at
version 2.10 (beta). It fixes the issue with the Intel graphics driver
on Windows 10.
