In order for this driver to be shared across the iop architectures the iop3xx and iop13xx header files are modified to present a common interface for the iop_wdt driver. Details: * iop13xx supports disabling the timer while iop3xx does not. This requires a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code. * The heartbeat interval is derived from the internal bus clock rate, so this this patch also exports the tick rate to the iop_wdt driver.
