HACK: Modify storage device spinup timeout

Previously the timeout was raised to 20s to work around a quirk on a
certain SSD after power wash / dev mode transition. After discussion
with the drive vendor, the worst-case delay is actually 23s. Though we
have not yet seen delays > 14s, bump the timeout to 25s to accomodate
the worst-case theoretical delay.

BUG=chrome-os-partner:23267
TEST=Compile only.
