BUTTERFLY-FIRMWARE: Check keyboard more often in recovery mode

Currently we check the keyboard each 250ms. This makes for a pretty choppy
experience when changing languages. Change to check every 20ms, without
changing the disk check interval (which remains 1s).

BUG=chrome-os-partner:15396
BRANCH=butterfly
TEST=manual, verify basic firmware functions.
