Subject[PATCH 2/2] drm: add more MMU dependencies
Date
Many DRM drivers only work with an MMU, and after the patch to enable
core DRM support without MMU, we already had one fixup for many of them.
The etnaviv, armada and msm drivers were missed and have the same problem:

warning: (DRM_ETNAVIV) selects IOMMU_SUPPORT which has unmet direct dependencies (MMU)
warning: (DRM_I915 && DRM_MSM && DRM_ETNAVIV) selects SHMEM which has unmet direct dependencies (MMU)
drivers/gpu/drm/armada/armada_gem.o: In function `armada_gem_vm_fault':
armada_gem.c:(.text.armada_gem_vm_fault+0x14): undefined reference to `vm_insert_pfn'
arch/arm/mm/dma-mapping.c: In function '__iommu_alloc_remap':
arch/arm/mm/dma-mapping.c:1390:4: error: 'VM_ARM_DMA_CONSISTENT' undeclared (first use in this function)
arch/arm/mm/dma-mapping.c:1456:31: error: 'atomic_pool' undeclared (first use in this function); did you mean 'atomic_xor'?

Fixes: 011cda589938 ("drm: fix compilations issues introduced by "drm: allow to use mmuless SoC"")
Fixes: 62a0d98a188c ("drm: allow to use mmuless SoC")
