bb_retimer: Reduce retry delay to 10ms
This reduces the delay between poll intervals of the burnside bridge
register accesses. A 10 ms delay is typically sufficient to achieve a
successful register read if the first register read failed.
BRANCH=none
BUG=none
TEST=with added timestamps, observed register accesses succeed after a
10ms delay.
