[ Upstream commit f8c6bfc612b56f02e1b8fae699dff12738aaf889 ]

The horizontal blanking periods are too short, as the values are
specified for a single LVDS channel. Since this panel is dual LVDS
they need to be doubled. With this change the panel reaches its
nominal vrefresh rate of 60Fps, instead of the 64Fps with the
current wrong blanking.

Philipp Zabel added:
The datasheet specifies 960 active clocks + 40/128/160 clocks blanking
on each of the two LVDS channels (min/typical/max), so doubled this is
now correct.

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.
