xbee: add support for multiple XBee interfaces 

XBEE_RESET_N_GPIO and XBEE_SLEEP_RQ_GPIO can now be comma-separated lists of
GPIO indexes instead of just a single index. Modify the xbee-init script to
support this change and modify the sed script in xbee.bb to allow commas
in the aforementioned variables.
