Subject: [PATCH v2 6/7] drm/panfrost: Add dependency on io-pgtable-arm format module

The Panfrost DRM driver depends on the availability of the ARM LPAE
io-pgtable format code to work properly. In preparation for having the
io-pgtable formats as modules, add a "pre" dependency with
MODULE_SOFTDEP() to ensure that the io-pgtable-arm format module is loaded
before loading the Panfrost DRM driver module.
