Move framebuffer vmap code from shadow-buffered plane state into the new interfaces drm_gem_fb_vmap() and drm_gem_fb_vunmap(). These functions provide mappings of a framebuffer's BOs into kernel address space. No functional changes.

v2:

• using [static N] for array parameters enables compile-time checks
• include <drm/drm_fourcc.h> for DRM_FORMAT_MAX_PLANES (kernel test robot)
