mainboard/google/zoombini/variants/meowth: Fix USB OC settings
Set USB2 port 0 & 1 to use OC2 and OC3 respectively. Previous settings
were causing false overcurrent conditions as OC0 and OC1 were used for
other purposes.
Remove initialization of unused usb3 ports, and configure the ports we
use (usb3 ports 0 & 1) to use OC2 and OC3, respectively.
BUG=b:72250084
BRANCH=none
TEST=Verify meowth can recognize and boot off a kernel on USB drive.
