I was going back and forth about mentioning this in the commit message
and we could off on this one until someone confirms that the
corresponding calibration data can (or should) be used for the X13s.

Note that there is no other match for

	'bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=140'

in the new board-2.bin.
