[RESEND][PATCH v3 15/26] drm: kirin: Move channel formats to driver data

[John Stultz <john.stultz@xxxxxxxxxx>]

From: Xu YiPing <xuyiping@xxxxxxxxxxxxx>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the channel
format arrays into the kirin_drm_data structure.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.
