zork: add a LTE present bit in fw_config
The up-to-date program/zork/program.star has a new LTE_PRESENT bit in
the fw_config.
Define it, so we can use it to steer the USB 3 mux for the LTE modem.

BRANCH=zork
TEST=On a vilboz360 LTE, program the CBI as for the next production
batch (e.g. 'sudo ectool cbi set 6 0x20099200 4') then run with the
next CL and see the LTE modem enumerated as USB 3.
