drm: lcdif: Check consistent bus format and flags across first bridges
The single LCDIF embedded in i.MX93 SoC may drive multiple displays simultaneously. Check bus format and flags across first bridges in ->atomic_check() to ensure they are consistent. This is a preparation for adding i.MX93 LCDIF support.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
