watchdog: Convert orion_wdt driver to watchdog core

Convert orion_wdt driver to use watchdog framework API.

---
Hi Jason, Andrew,
I don't have this hardware handy.
I'd appreciate if you can review and test this patch.

Thanks,
Axel
v3: Base on Jason's comment, platform data is changing soon with devicetree
support, so I don't change the coding style for getting tclk from pdata. I keep the whitespace change for WDT_EN in this version, as it makes the code looks better and I don't think it worth to send a separate patch for fixing a whilespace.
v2: v1 does not apply to current tree. so I re-generate this patch.

Axel,

Sorry for the delay, been a busy week. I'm getting the following error:

drivers/watchdog/orion_wdt.c:133:2: error: unknown field 'get_timeleft' specified in initializer
drivers/watchdog/orion_wdt.c:133:2: warning: initialization from incompatible pointer type

What tag did you base this off of? Are there any dependencies not in mainline?

I based off of v3.3 with the following merged:

git://git.infradead.org/users/jcooper/linux-kirkwood.git kirkwood_dt_for_3.4_v3

thx,

Jason.

I generate the patch base on linux-next tree.
I just checked Linus' tree and this patch is appliable to Linus' tree. The required commit[1] is alread merged to Linus' tree now. Can you check it again?
Thanks.

Ah, much better. I rebased it against v3.4-rc1 now that it's out. Compiles without problems. I'll test this weekend most likely. I don't have my watchdog code in front of me atm.

thx,

Jason.
