drm/i915/gvt: Fix emulated vbt size issue
The emulated vbt doesn't tell its size correctly. According to the
intel_vbt_defs.h, vbt_header.vbt_size should the size of VBT (VBT Header,
BDB Header and data blocks), and bdb_header.bdb_size should be the size
of BDB (BDB Header and data blocks).
This patch fixes the issue and lets vbt provided by GVT-g pass the guest
i915's sanity test.
v2: refine the commit message. (Zhenyu)
