A recent switch to a dedicated AP807 compatible string for the Xenon SD/MMC controller result in the driver not being probed when using updated device tree with the older kernel revisions. It may also be problematic for other OSs/firmware that use Linux device tree sources as a reference. Resolve the problem with backward compatibility by restoring a previous compatible string as secondary one. Signed-off-by: Marcin Wojtas <redacted>
