Okay I thought this would be easy, but it seems not.  This is what I
came up with:

-                printf("mck clock rate: %lu\n", clk_get_rate(nc->mck));
+                printf("%s rate: %lu MHz\n",
+                       nc->mck->dev->name ? nc->mck->dev->name : "mck clock",
+                       clk_get_rate(nc->mck) / 1000000);

And this is the output on sam9x60 with CONFIG_CLK_CCF enabled:

    pmc at fffffc00 rate: 200 MHz

The corresponding line from `clk dump` is:

     200000000            5        |       |           |   `-- mck_div

That name, I don't get it where to get that one.
