Currently, having libgfxinit try to enable VGA will result in a hang.
On the Asrock B85M Pro4, DDI E (VGA) was not being enabled in coreboot,
so it did not hang. However, this renders Linux's i915 driver unable to
use VGA at all. In absence of monitors with digital inputs, this is bad.
To work around this problem, mark DDI E as enabled, and comment out VGA
from gma-mainboard.ads for the time being. This allows one to use a VGA
monitor, even if it only works after Linux drivers have taken over.

According to the Wilco EC spec the BTSC bit of PWSR is always cleared
when PWSR is read so that battery status change events are only
triggered one time. Testing of the Wilco EC has verified this behavior.
This changes the way in which the battery status change bit is used from
checking the bit state against the previous value to always issuing a
battery event when the BTSC bit is set. The other bits in PWSR indicate
state directly and do not behave like the BTSC bit.

This change adds mem_list_variant.txt that contains the list of
memory parts used by halvor and Makefile.inc generated by
gen_part_id.go using mem_list_variant.txt.
In the final change of the series, all volteer variants will be
switched from using the current SPDs to new auto-generated SPDs.
Differences in auto-generated SPD from current SPD are as follows:
