Subject: [PATCH v1] drm/panel: simple: set bpc field for logic technologies displays

From: Aishwarya Kothari <aishwarya.kothari@...adex.com>

In case bpc is not set for a panel it then throws a WARN(). Add bpc to
the panels logictechno_lt170410_2whc and logictechno_lt161010_2nh.

Fixes: 5728fe7fa539 ("drm/panel: simple: add display timings for logic technologies displays")
