uses the same panel as the ETM0700G0BDH6. It differs
in the hardware design for the backlight and the
touchscreen i2c interface. As the new display type has
different requirements for drive-strengths on the i2c-bus,
add an additional compatible to allow the handling of it or warn
about incompatible cpu and display combinations.

Remove all drm_panel_detach() calls from all panel drivers and update
the kerneldoc for drm_panel_detach().

Setting the connector and drm to NULL when the DRM panel device is going
away hardly serves any purpose. Usually the whole memory structure is
freed right after the remove call. However, calling the detach function
from the master DRM device, and setting the connector pointer to NULL,
has the logic of marking the panel again as available for another DRM
master to attach. The usual situation would be the same DRM master
device binding again.

Convert the sharp lq123p1jx31 from using a fixed mode to specifying a
display timing with min/typ/max values. This allows us to capture the
timings set forth in the datasheet as well as the additional values that
we've cleared with the display vendor to avoid interference with the
digitizer on the Samsung Chromebook Plus (kevin).

A follow-on patch will specify the override mode for kevin devices.
