The third and fourth patch are related: the latter strictly depends on
the former. The idea behind these two patches is basically to convert
the "keep the ethernet clocks enabled by calling clk_enable()" hack
into a simpler and cleaner usage of the CLK_IGNORE_UNUSED flags which
prevent these clocks from being ever gated.

Hi Ezequiel

This should work, but what would be nicer is to look and see if there
is a node in DT for each device. If it does not have a node, don't set
CLK_IGNORE_UNUSED, so that the clock does get turned off, and we save
a bit of power. Quite a few of the kirkwood devices only have one
ethernet.

Good idea. I'll take a look at it.
