watchdog: ARM mpcore Improvements

** This still doesn't make it workable **

Hi,

ARM mpcore watchdog isn't workable and so is marked broken in the first patch of the series. Reasons are mentioned in 01/14 and important links are shared too.

Other are basically improvements which I have written more than a year back. I am just pushing them through as they still improve the driver (or broken driver). They still don't fix the issues pointed out by Marc Zyngier earlier. But as these are generic improvements I don't see why they can't be applied, even to a still broken driver.

I don't want somebody to waste time reinventing these patches, rather they can work on fixing the issues due to which this driver is broken.

I don't have hardware & time to fix the BROKEN part of this driver now :(

Link to the last version, nothing much changed after that. Just a resend:
