gingerbread: Set default USB-A 3.1 Gen 2 port current limit to 1.5A
USB3.1 gen2 ports support either 900 or 1500 mA current limits. The
current limt is controlled by 2 GPIO signals. This CL sets the default
values of those GPIO signals to enable the 1500 mA current limit to
avoid cases where the 900mA current limit is getting exceeded.
BUG=b:206059703
BRANCH=quiche
TEST=verify levels with gpioget
1* USB3_P3_CDP_EN
1* USB3_P4_CDP_EN
