Host command for USB PD role and mux control
This allows us to control PD role and type-C mux through ectool.
BUG=None
TEST=Change role/mux on samus using ectool:
$ ./ectool --interface=lpc --dev 1 usbpd 0 usb
-> In EC console, 'typec 0' shows 'Superspeed USB1'
$ ./ectool --interface=lpc --dev 1 usbpd 0 sink
-> In EC console, 'pd 0 state' shows 'force sink'
BRANCH=None
