drm/etnaviv: replace license text with SPDX tags This replaces the repetitive GPL-2.0 license text in code and header files with the SPDX tags. Generated hardware headers aren't changed, as any changes there need to be done in the upstream rnndb repository.

drm/etnaviv: remove IOMMU dependency Using the IOMMU API to manage the internal GPU MMU has been an historical accident and it keeps getting in the way, as well as entangling the driver with the inner workings of the IOMMU subsystem. Clean this up by removing the usage of iommu_domain, which is the last piece linking etnaviv to the IOMMU subsystem. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

drm/etnaviv: rename etnaviv_iommu_domain_restore to etnaviv_iommuv1_restore This function has external visibility and only handles the Vivant IOMMU version 1. Rename to make this more clear and allow a clear separation of the different IOMMU versions. Also drop the domain parameter, as we can infer it from the GPU we are dealing with.
