Hans de Goede ff3bcdc9b5 drm/i915: Fix not finding the VBT when it overlaps with OPREGION_ASLE_EXT 
commit 998d75730b upstream.

If there is no OPREGION_ASLE_EXT then a VBT stored in mailbox #4 may
use the ASLE_EXT parts of the opregion. Adjust the vbt_size calculation
for a vbt in mailbox #4 for this.

This fixes the driver not finding the VBT on a jumper ezpad mini3
cherrytrail tablet and on a ACER SW5_017 machine.
