[PATCH 1/2] ARM: sa1100: add missing include of linux/io.h

[Arnd Bergmann]

After c00184f9ab4 "ARM: sa11x0/pxa: convert OS timer registers to IOMEM",
pleb_defconfig produces this new warning:

arch/arm/mach-sa1100/cpu-sa1100.c: In function 'sa1100_update_dram_timings':
arch/arm/mach-sa1100/cpu-sa1100.c:153:3: error: implicit declaration of function 'IOMEM'

Adding linux/io.h to the file using the __REG() macro avoids the warning.
In the long run, we still need to convert the entire file to use
readl/writel rather than directly derefencing the pointer, but this makes
it compile again.
