drm/tegra: fb: Implement ->fb_mmap() callback This fixes hangs with legacy applications that use the mmap() syscall on the fbdev device to map framebuffer memory. The fbdev implementation for mmap() creates a mapping that conflicts with DRM usage and causes a hang when the memory is accessed through the mapping.
