Alec Berg 1aa13eb648 samus: allow booting without a battery

When there is no battery, add a delay in power sequencing to
allow time for PD MCU to negotiate to 20V. This is a temporary
solution to allow booting without a battery for a factory.

BUG=chrome-os-partner:31583
BRANCH=none
TEST=Boot without a battery 10 times successfully. Also looked
at timestamps on console. PD MCU tends to successfully negotiate
before 370ms. With this added delay, the EC will come out of S5
at around 660ms.
