watchdog: MIPS: lantiq: implement OF support and minor fixes
Add support for OF. We also apply the following small fixes
* reduce boiler plate by using devm_request_and_ioremap
* sane error path for the clock
* move LTQ_RST_CAUSE_WDTRST to a soc specific header file
* add a message to show that the driver loaded
