Maxim Sobolev cd86367a5a When enabling A20 put upper limit on amount of time we wait for the keyboard
controller to get ready (65K x ISA access time, visually around 1 second).
If we have wait more than that amount it's likely that the hardware is a
legacy-free one and simply doesn't have keyboard controller and doesn't
require enabling A20 at all.

This makes cdboot working for MacBook Pro with Boot Camp.
