Subject: [PATCH] hwdb: Apply existing accel orientation quirk to all
Chromebooks
The cros-ec-accel and cros-ec-accel-legacy kernel modules internally
correct for the board-specific accelerometer mounting orientations.
Their sensor outputs are in a standard reference frame consistent across
different boards, so the orientation matrix already added for a number
of devices should apply to every device using cros-ec accelerometers.
The different matrix for the 'Nocturne' board seems to be an error.
Replace the existing hwdb rules for select Chromebooks with generic
rules that apply to all Chromebooks.
(cherry picked from commit 1800f7098a3e91a1d28697ef11a15e4b4193d21f)
