Log:
OLPC XO 1.5: ALPS keyboard support; Trust the EC.

The ALPS keyboard need 500ms to startup before you can successfully
talk to it.  The previous keyboard routines would try to probe
at the same time that the EC is trying to detect what keyboard
controller is installed.  When OFW dosen't get a response
it assumes there is no keyboard.

Now OFW assumes that the EC is properly detecting the keboard
controller (Which is does as of Ver 1.9.30) and the only command
it sends is the scan enable.
