udev: hwdb: Add rules to match cros-ec-accel by 'location' sysfs file
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.
