Xilinx Axi Watchdog driver conversion to driver model

Hi,

this is moving MB watchdog to DM. I have taken v2 from Shreenidhi and did some changes to speedup upstreaming because I need this for my gpio work. Removing watchdog in the first patch is not big deal because this is generic platform and adresses are fake.

Sending only last patch because the rest was already applied and there are patches which depends on that.

Thanks,
Michal
