Add the basic infrastructure to periodically execute code, e.g. all 100ms. Examples for such functions might be LED blinking etc. The functions that are hooked into this cyclic list should be small timewise as otherwise the execution of the other code that relies on a high frequent polling (e.g. UART rx char ready check) might be delayed too much. This patch also adds the Kconfig option CONFIG_CYCLIC_MAX_CPU_TIME_US, which configures the max allowed time for such a cyclic function. If it's execution time exceeds this time, this cyclic function will get removed from the cyclic list. How is this cyclic functionality executed? The following patch integrates the main function responsible for calling all registered cyclic functions cyclic_run() into the common WATCHDOG_RESET macro. This guarantees that cyclic_run() is executed very often, which is necessary for the cyclic functions to get scheduled and executed at their configured periods. This cyclic infrastructure will be used by a board specific function on the NIC23 MIPS Octeon board, which needs to check periodically, if a PCIe FLR has occurred.
