The BL1 stage setup code for ARM platforms sets up the SP805 watchdog controller as the secure watchdog. But not all ARM platforms use SP805 as the secure watchdog controller. So introduce two new ARM platform code specific wrapper functions to start and stop the secure watchdog. These functions then replace the calls to SP805 driver in common BL1 setup code. All the ARM platforms implement these wrapper functions by either calling into SP805 driver or the SBSA watchdog driver.
