Cr50: Update the USB VID:PID:subclass constants
The device-specific subclass used for Non-HC firmware updates is
in the spreadsheet now, so we can rename the macros to be
"official".
BUG=chrome-os-partner:49962
BRANCH=none
TEST=make buildall; test on cr50
make BOARD=cr50 (plus whatever signing magic works for you)
make -C extra/usb_updater
./extra/usb_updater/usb_updater build/cr50/ec.bin (sudo if needed)
Note that you may need to rebuild ec.bin in order to see any
difference after the update. If the A & B images are identical,
the RO bootloader always picks A.
