eve: Do not attempt to set 1.5A USB config
The EC attempts to limit USB ports to 1.5A if a device is plugged
into both ports, but this ends up with no power to the ports instead.
Until this can be debugged with the right equipment just pretend we
can do 3A to both ports so factory tests can pass.
BUG=chrome-os-partner:61431
BRANCH=none
TEST=plug device into both ports on P1 board and see that they work
