ARM: davinci: da8xx: fix multiple watchdog device registration
Fix multiple watchdog device registration on da8xx devices due to davinci_init_devices blindly registering watchdog device. Fix this by getting rid of the initcall and instead registering watchdog for each soc. Signed-off-by: Sekhar Nori <nsekhar@ti.com>
