The 25 MHz reference clock has better stability so its use is preferred over the
core clock. Changes the Armada 375 clock initialization to use this reference
clock. To ensure the driver is compatible with an old devicetree, also provide
a fallback path which will silently return to the previous behavior.

Hi Ezequiel

There is now quite a lot of code in orion_wdt.c which is not relevant
to Orion5x and Kirkwood. Would it be possible to put some of it inside
a #ifdef MACH_MVEBU_V7?

Hum.. I found ifdefs scary, so I tend to avoid them if at all possible.
Just did a quick hack enclosing all the armada-xxx stuff around #if 0
and here's the result:

$ ./scripts/bloat-o-meter ~/linux/.builds/mvebu_v7/drivers/watchdog/orion_wdt.o ~/linux/.builds/orion5x/drivers/watchdog/orion_wdt.o
add/remove: 0/0 grow/shrink: 1/4 up/down: 12/-80 (-68)

orion_start                                  120      88     -32
orion_wdt_ping                                80      44     -36

To be honest, I don't think it's worth the ugliness.
