microblaze: Fix watchdog initialization

The patch:
"blackfin: Move blackfin watchdog driver out of the blackfin arch folder."
(sha1: e9a389a18477c1c57a0b30e9ea8f4d38c6e26e63)
changed hw_watchdog_init() prototype which didn't match
with Microblaze one.
This patch fixes the driver and Microblaze initialization.
