[PATCH] drm/i915/fbc: Add sizes to info message about reducing fb size

[Paul Menzel]

The info message currently does not contain any information, how much
the stolen memory size should be increased.

    [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS.

To be more useful to the user, add the sizes to the message.
