drivers/video/fbdev/atyfb: Clarify ioremap() base and length used

Adjust the ioremap() call for the framebuffer to use the same
values we later use for the framebuffer. This will make it
easier to review the next change.

The size of the framebuffer varies but since this is for PCI we
*know* this defaults to 0x800000. atyfb_setup_generic() is
*only* used on PCI probe.

No functional change.
