[PATCH 5/8] drm/framebuffer: Use actual bpp for DRM_IOCTL_MODE_GETFB

[Geert Uytterhoeven]

When userspace queries the properties of a frame buffer, the number of
bits per pixel is derived from the deprecated drm_format_info.cpp[]
field, which does not take into account block sizes.

Fix this by using the actual number of bits per pixel instead.
