plat/arm: introduce wrapper functions to setup secure watchdog
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.
