FAFT: Use firmware_screen time to when pressing ctrl-D repeatedly
This patch replaces the time allowed for firmware_DevScreenTimeout
to press ctrl-D from a hard-coded 20sec (increased in CL:240105) to
firmware_screen * 2. Since firmware_screen is currently 10sec by
default, this will not have an impact on most platforms.
The idea for firmware_DevScreenTimeout is to obtain an aggessively
low dev mode boot time value by spamming the AP with ctrl-D every
half second. So firmware_screen in this case acts as a ceiling and
we expect that the AP will be ready to accept ctrl-D earlier.

BRANCH=firmware-veyron
TEST=firmware_DevScreenTimeout passes more reliably on veyron_mickey
