Watchdog driver implementation for CC26XX.
============================================================================
The Watchdog header file for CC26XX should be included in an application as follows:
The general SPI API should be used in application code, i.e. SPI_open() should be used instead of SPICC26XXDMA_open(). The board file will define the device specific config, and casting in the general API will ensure that the correct device specific functions are called.
This Watchdog driver implementation is designed to operate on a CC26XX device. Once opened, CC26XX Watchdog will count down from the reload value specified in the WatchdogCC26XX_HWAttrs. If it times out, the Watchdog interrupt flag will be set, and a user-provided callback function will be called. If resets have been enabled in the Watchdog_Params and the Watchdog Timer is allowed to time out again while the interrupt flag is still pending, a reset signal will be generated. To prevent a reset, Watchdog_clear() must be called to clear the interrupt flag.
The reload value from which the Watchdog Timer counts down may be changed during runtime using Watchdog_setReload().
Watchdog_close() is not supported by this driver implementation.
By default the Watchdog driver has resets turned on. However, they may be turned off in the Watchdog_Params which allows the Watchdog Timer to be used like another timer interrupt. This functionality is not supported by all platforms, refer to device specific documentation for details.

To have a user-defined function run at the warning interrupt, first define a void-type function that takes a Watchdog_Handle cast to a UArg as an argument such as the one shown below.
#include <stdint.h>
#include <stdbool.h>
#include <ti/drivers/Watchdog.h>
#include <ti/sysbios/family/arm/m3/Hwi.h>
