The cros-ec-accel devices report their mounting location by the 'label' sysfs file only since Linux v6.0. With earlier kernels, a nonstandard 'location' file reports this, but slightly differently (lid instead of display) [1]. Add udev rules to import the correct hwdb entries based on this 'location' file for cros-ec-accel devices, so that the base-mounted accel matrix has the correct value for older kernels as well.
