DRM: Armada: Add Armada DRM driver This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.

drm/armada: Move GEM BO to drm_framebuffer Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.

drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create() Drivers shouldn't clobber the passed in addfb ioctl parameters. i915 was doing just that. To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create().

drm/armada: move armada_drm_mode_config_funcs to armada_drv.c Move the armada_drm_mode_config_funcs to armada_drv.c, since this now has less to do with FBs than it does with general mode configuration. In doing so, we need to make armada_fb_create() visible to armada_drv.c, which reveals a function name clash with armada_fbdev.c. Rename the version in armada_fbdev.c.
