drm/i915/bios: Update VBT driver feature block version numbers
While the spec does claim that most of the driver feature flags
start from BDB version 165, reality and some VBIOS code disagrees.
The VBIOS code says it starts from version 159, and my ILK
with version 162 definitely has these things already in its
VBT. Update the version number comments to say 159+ for all
the bits that seem relevant for pre-hsw hardware.
