ARM: sa11x0/pxa: convert OS timer registers to IOMEM

Browse Source 
Make the OS timer registers have IOMEM like properities so they can
be passed to readl_relaxed/writel_relaxed() et.al. rather than being
straight volatile dereferences.  Add linux/io.h includes where
required.

linux/io.h includes added to arch/arm/mach-sa1100/cpu-sa1100.c,
 arch/arm/mach-sa1100/jornada720_ssp.c, arch/arm/mach-sa1100/leds-lart.c
 drivers/input/touchscreen/jornada720_ts.c, drivers/pcmcia/sa1100_shannon.c
from Arnd.

This fixes these warnings:

arch/arm/mach-sa1100/time.c: In function 'sa1100_timer_init':
arch/arm/mach-sa1100/time.c:104: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type
arch/arm/mach-pxa/time.c: In function 'pxa_timer_init':
arch/arm/mach-pxa/time.c:126: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type
