cm-x270.c with rtc, sound and touchscreen support

For the Compulab cm-x270 module with kernel 2.6.20 I modified the cm-x270.c
file to get the rtc, sound and touchscreen working. I also had to change
several kernel options.

For sound I included:
> CONFIG_SOUND=y
> CONFIG_SND=y
> CONFIG_SND_TIMER=y
> CONFIG_SND_PCM=y
> CONFIG_SND_SUPPORT_OLD_API=y
> CONFIG_SND_VERBOSE_PROCFS=y
> CONFIG_SND_AC97_CODEC=y
> CONFIG_SND_PXA2XX_PCM=y
> CONFIG_SND_PXA2XX_AC97=y

For the touchscreen I included:
> CONFIG_INPUT_EVDEV=y
> CONFIG_INPUT_TOUCHSCREEN=y
> CONFIG_TOUCHSCREEN_UCB1400=y

For the rtc I included:
> CONFIG_RTC_CLASS=y
> CONFIG_RTC_HCTOSYS=y
> CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
> CONFIG_RTC_INTF_SYSFS=y
> CONFIG_RTC_INTF_PROC=y
> CONFIG_RTC_INTF_DEV=y
> CONFIG_RTC_DRV_V3020=y

The cm-x270.c file is normally supplied bij patch "0002-cm-x270-base.patch" I
included the working cm-x270.c as an attachment. I also attached my working
kernel config file "defconfig".
