[WATCHDOG] at32ap700x_wdt: add support for boot status and add fix for silicon errata
This patch enables the watchdog to read out the reset cause after a boot and
provide this to the user.
The driver will now also return -EIO if probed when booting from a watchdog
reset. This is due to a silicon errata in the AT32AP700x devices.
Detailed description and work-arounds can be found in the errata section of the
datasheet avilable from
