Instead of using the default resolution of 800*600 for the pointing
device of xen-kbdfront try to read the resolution of the (virtual)
framebuffer device. Use the default as fallback only.
Signed-off-by: Juergen Gross <jgross@suse.com>

V3: add case of late framebuffer registration (Oleksandr Andrushchenko)
V2: get framebuffer resolution only if CONFIG_FB (Dmitry Torokhov)

Instead of using the default resolution of 800*600 for the pointing
device of xen-kbdfront try to read the resolution of the (virtual)
framebuffer device. Use the default as fallback only.

V3: add case of late framebuffer registration (Oleksandr Andrushchenko)
V2: get framebuffer resolution only if CONFIG_FB (Dmitry Torokhov)
