rambi: Support USB port power control
Rambi shares several of the control signals (CTL1, ILIM_SEL) between
both ports, and hard-wires some of the others (CTL2, CTL3). It still
has separate enable lines for each port.
BUG=chrome-os-partner:18343
BRANCH=none
TEST=boot system; gpioget shows (in part)
1 USB_CTL1
0 USB_ILIM_SEL
1 USB1_ENABLE
1 USB2_ENABLE
Then do 'apshutdown' and gpioget shows
1 USB_CTL1
0 USB_ILIM_SEL
0 USB1_ENABLE
0 USB2_ENABLE
