Fourth round of the patchset adding support for watchdog on Armada 375 and
Armada 38x SoCs.

The new Armada 375/385 SoCs have two registers for the watchdog RSTOUT:

 1. It has a dedicated register (similar to the one in A370/XP)
 2. Also has a bit in a shared RSTOUT register.

Therefore, in order to support this two-folded RSTOUT, we extend the 'reg'
property in the watchdog devicetree and require a new pair of cells to specify
the shared RSTOUT.

On the driver side, we need to implement per-SoC stop() and enabled()
functions. Such somewhat complex infrastructure is needed to ensure the driver
performs proper reset of the watchdog timer, by masking and disabling the
RSTOUT before the interrupt is enabled.

I've pushed a branch so people can test this easily, e.g. ensuring
no regressions on Dove, Kirkwood and A370/XP:

Ezequiel,

Although, I just saw below that you actually already tested on Dove,
you can add my

Great, thanks!
