fbdev: au1100fb: Make driver compilable on non-mips platforms

Browse source 
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.
