drm/msm: mark the fbdev framebuffer as system memory
msm_fbdev_driver_fbdev_probe() points screen_buffer at a kernel virtual
mapping of the GEM object and uses the deferred sysmem fb ops, but never
sets FBINFO_VIRTFB. The framebuffer core then assumes the memory is not
in the virtual address space and warns on the first console draw:
fb0: sys_fillrect: framebuffer is not in virtual address space.
The drm_fbdev_dma, drm_fbdev_shmem and drm_fbdev_ttm helpers all set the
flag for system memory. Do the same here.
