cr50: default to CCD PHY
While kevin is still in development default to connecting to the CCD PHY
instead of the AP PHY. This will automatically enable CCD instead of
having to rely on things working to detect the debug accessory and
switch to the proper PHY.
We also disable the TX lines to the AP and EC, in case servo is
connected. To turn them on manually, use these console commands:
rw 0x40060040 74
rw 0x400600c8 78
pinmux
gpiocfg
BUG=chrome-os-partner:50700,chrome-os-partner:52281,http://crosbug.com/p/52322
BRANCH=none
TEST=hook up suzy q to kevin. Run 'lsusb -vd 18d1:5014' and check that a
device appears.
