Using global data to store device specific data is a bad pattern that
breaks if there is more than one device. So expand driver data and drop
the global variables.
While there is probably no machine that has two or more au1100fb
devices, this makes the driver a better template for new drivers and
saves some memory if there is no such bound device.
bloat-o-meter reports (for ARCH=arm allmodconfig + CONFIG_FB_AU1100=y
and ignoring the rename of the init function):

I think this doesn't need a Fixes line, but if you want, it would be:
Fixes: 3b495f2bb749 ("Au1100 FB driver uplift for 2.6.")
Fixes: f77f50ca1a23 ("[PATCH] au1100fb: add power management support")

%zu is the dedicated type for size_t. %d only works on 32bit
architectures where size_t is typedef'd to be unsigned int. (And then
the signedness doesn't fit, but `gcc -Wformat` doesn't stumble over this.
Also the size of dma_addr_t is architecture dependant and it should be
printkd using %pad (and the value passed by reference).
This prepares allowing this driver to be compiled on non-mips platforms.

The header asm/mach-au1x00/au1000.h is unused apart from pulling in
<linux/delay.h> (for mdelay()) and <linux/io.h> (for KSEG1ADDR()). Then
the only platform specific part in the driver is the usage of the KSEG1ADDR
macro, which for the non-mips case can be stubbed.

The global wrappers also have the advantage to do stricter format
checking, so the pr_devel formats are also checked if DEBUG is not
defined. The global variants only check for DEBUG being defined and not
its actual value, so the #define to zero is dropped, too.
There is only a slight semantic change as the (by default disabled)
debug output doesn't contain __FILE__ any more.
