Disable watchdog registation when kernel is build without watchdog functionality, and enable watchdog core otherwise. This removes compile errors like the one below: drivers/rtc/rtc-pcf2127.o: in function `pcf2127_probe.constprop.3': rtc-pcf2127.c:(.text.unlikely+0x2c8): undefined reference to `devm_watchdog_register_device' Watchdog feature in chip will always be configured as this is safe to do in both cases and minimize code churn.
