Actually mach-mv78xx0 don't use orion_wdt driver. In KConfig it depends
on ARCH_ORION5X, ARCH_KIRKWOOD or ARCH_DOVE but not ARCH_MV78XX0.

Moreover the register mapping is not exactly the same than the one used for
orion5x, kirkwood and dove.

But mach-orion5x still uses the orion_wdt driver and is not yet fully
converted to DT.
