drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+ This driver will be used to support Mesa on the Broadcom 7268 and 7278 platforms. V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.

drm/v3d: add CONFIG_MMU dependency Without CONFIG_MMU, we get a link error: drivers/gpu/drm/v3d/v3d_bo.o: In function `v3d_gem_fault': v3d_bo.c:(.text+0x3ca): undefined reference to `vm_insert_mixed' The other drivers with this problem already depend on CONFIG_MMU, so let's do the same thing here.

drm/v3d: Use the new shmem helpers to reduce driver boilerplate. The new shmem helpers from Noralf and Rob abstract out a bunch of our BO creation and mapping code. v2: Use the new sgt getter, and flag pages as dirty before freeing. v3: Remove the mismatched put_pages.
