watchdog: sp5100_tco: Add SB8x0 chipset support

The regression was introduced as of v3.8-rc1.

I see that you are the author of this patch, so I wanted to run this by
you. I was thinking of requesting a revert for v3.8, but I wanted to
get your feedback first.
Please check out the attached patches first (They are allready in
Thanks for the feedback, Wim. I'll let you know if the patches resolve this

Kind regards,
Thank you for your information, and sorry for the late reply.

I think that I will get rid of code that re-programming the chipset
registers, if my patch set doesn't resolve the problem.
I'm waiting for your reply at the moment.
