soc/intel/cannonlake: Add configs for USB 3.1 Gen2 EV settings 

Add configs for USB 3.1 Gen2 EV settings so that people can set the
EV settings per board in device tree.

BUG=b:150515720
BRANCH=none
TEST=build coreboot and fsp with enabled fw_debug.
     Flashed to puff and checked the log.
     All usb configs were set correctly.
