Fizz has two power sources: barrel jack and type-c port. It
selects a power source at boot and does not dynamicall switch
to the other ports after that.
Fizz initializes all power suppliers of all ports to zero then
initialize the source supplier (barrel jack or type-c port).
When both sources are provided, it prefers a barrel jack. This
detection is done by reading the voltage on PPVAR_PWR_IN.
If barrel jack is detected as a sink, type-c port works as a
source only. If type-c port is detected as a sink, type-c
port works as a sink only.
Fizz does not have a battery. So, battery module is removed.

BRANCH=none
TEST=Boot on both type-c & barrel jack.
