Watchdog driver implementation for MSP432.
============================================================================
The Watchdog header file for MSP432 should be included in an application as follows:
Refer to Watchdog.h for a complete description of APIs & example of use.
The MSP432 Watchdog Timer will cause resets at an interval based on the count calculated from the clock source and clock divider specified in the WatchdogMSP432_HWAttrs. By default the Watchdog driver has resets turned on. This means that if Watchdog_clear() is not called to reset the Watchdog timer before it times out, a reset will be generated. Watchdog_close() will stop the Watchdog timer. To restart it again, Watchdog_open() must be called.
Opening the Watchdog driver with resets turned off (using the resetMode parameter) allows the Watchdog Timer to be used like another timer interrupt. The callback fxn provided in the params will be executed when the timer expires.
Note: The Watchdog_Params callbackFxn and debugStallMode are not used in this implementation nor is the Watchdog_setReload() API.

intPriority is the Watchdog timer's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. If the driver uses the ti.drivers.ports interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().
