With the generic watchdog driver now implemented, this patch removes some legacy stuff from the MPC8xx watchdog driver and its Kconfig integration. CONFIG_MPC8xx_WATCHDOG is completely removed and hw_watchdog_reset() is made static, as the watchdog will now get serviced via the DM infrastructure if enabled via CONFIG_WATCHDOG.
