Use SECOND and MSEC constants

We'd defined them in a number of different files.  This moves
definitions to timer.h, and uses them everywhere we have large delays
(since 10*SECOND is less typo-prone than 10000000).

Also add msleep() and sleep() inline functions.  No need for mdelay()
or delay(), since any delays that long should use sleep funcs instead
of spin-waiting.

BUG=chrome-os-partner:15579
BRANCH=none
TEST=boot system; taskinfo displays similar numbers to before
