accel-location: Handle cros-ec sensor location

Browse Source 
All devices with "Chromium embedded controllers have their display
sensor location set as "lid" and that sensor location is only
available through sysfs.

Prior to this commit, chromebooks with two accelerometers had their
base sensor being used as display.

See: f678d6da74/drivers/iio/common/cros_ec_sensors/cros_ec_sensors_core.c (L137)

Closes: #278
