Watchdog Timer Functionality / SDK Support

[BrentK-ADI]

This was discovered with the MAX32690, but may apply to other devices.

Per the user's guide, regarding the Watchdog timer, "The event flags are set even if the corresponding interrupt enable or reset enable are not enabled, and include the early interrupt flag and early event flag even if the window feature is disabled (WDTn_CTRL.win_en = 0).". With the currently SDK, there are no functions available to check the current state of the WDT Enable, Reset Enable or Interrupt enable flags, and requires manually accessing the peripheral registers.

Recommend the SDK be updated to include access to the enable fields, and the example application be modified to check WDT is enabled prior to checking the reset flags.
