pd: samus: do not request voltage within boost bypass deadband
Do not request a voltage that is within the deadband where we
aren't sure if the boost or the boost bypass is on.
BUG=chrome-os-partner:34938
BRANCH=samus
TEST=test on samus with zinger. change the deadband to [10V, 20V]
and see that we only negotiate to 5V. change the deadband to
[13V, 20V] and see that we negotiate to 12V. change the deadband
to [10V, 13V] and see that we negotiate to 20V.
