Fizz: Set PD operating power to 50W
This patch sets the PD operating power to 50W, which is the same as what
the AP requires to boot. Since Fizz doesn't have a battery to charge,
we're not interested in lower power.
BUG=none
BRANCH=none
TEST=Boot Fizz on Type-c adapter (87W, 60W). Verify it fails to boot on
on 45W charger.
