Convert drivers to use the API - devm_drm_panel_alloc().
There are a lot of occurences of the panel allocation across the
subsystem. Much thanks to Maxime for the semanic patch which actually
gives a list of panels allocated unsafely.

The changes to the list of panels that this script gives is done manually.
Part 1 of the series : https://patchwork.freedesktop.org/series/147082/
is already merged. Sending this next part that covers next 30 drivers.
Sending in batches for easier review.
Minor changes in this version: 2 alignment fixes and 2 refactor and
1 compilation fix.
This took a while to resend mainly due to being away (out of office),
workstation issues because of which lost the work directory that dim
had created and had to start afresh.
