[PATCH v2 1/2] ARM: sa1100: add missing include of linux/io.h

[arnd@arndb.de (Arnd Bergmann)]

After c00184f9ab4 "ARM: sa11x0/pxa: convert OS timer registers to IOMEM",
multiple defconfig files produce 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 all register accesses to use
readl/writel rather than directly derefencing the pointer, but this makes
it compile again.

v2: actually fix all call sites, rather than just the first one

We might want to put the #include directly into mach/SA-1100.h
instead, to be on the safe side.
