fbdev: Fix loading of module radeonfb on PowerMac
When the linux kernel is build with (typical kernel ship with Debian
installer):
CONFIG_FB=y
CONFIG_FB_OF=y
CONFIG_VT_HW_CONSOLE_BINDING=y
CONFIG_FB_RADEON=m
The offb driver takes precedence over module radeonfb. It is then
impossible to load the module, error reported is:
[ 96.551486] radeonfb 0000:00:10.0: enabling device (0006 -> 0007)
[ 96.551526] radeonfb 0000:00:10.0: BAR 0: can't reserve [mem 0x98000000-0x9fffffff pref]
[ 96.551531] radeonfb (0000:00:10.0): cannot request region 0.
[ 96.551545] radeonfb: probe of 0000:00:10.0 failed with error -16
This patch reproduce the behavior of the module radeon, so as to make it
possible to load radeonfb when offb is first loaded, see
commit a56f7428d753 ("drm/radeon: Add early unregister of firmware fb's").
