[PATCH v1 08/47] video: fbdev: atyfb: clarify ioremap() base and length used

[Luis R. Rodriguez]

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

This has no functional changes, it just adjusts
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.
