Subject: [PATCH 619/625] panfrost: compatibility with Baikal-M firmware from
 SDK-M 4.3

Added .compatible string so the driver can be used on Baikal-M
systems with firmware from SDK-M 4.3.

Note: the driver should be explicitly enabled with
enable_broken_machines=y module parameter

Update for 5.15.28
