This patch changes get_timer() for i.MX to return the time since
'base' instead of the time since the counter was at zero.

Symptom seen is flash timeout errors when erasing or programming a
sector using the common cfi flash code.

- Use i.MX watchdog timer for reset_cpu()
- Move reset_cpu() out of cpu/arm920t/start.S into the SoC specific
  subdirectories cpu/arm920t/imx/ and cpu/arm920t/s3c24x0/
  (now in interupts.c)

reset timers so it's save to use udelay() in timeout code.

- Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
- creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
- moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
- moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
  into cpu/arm920t/$(SOC)/
