[PATCH] ARM: kirkwood: Force nand platform device name

[Jamie Lentin]

The clk framework relies on device names to be constant. Pre-dt, the
NAND platform device was called "orion_nand" which is what the framework
expects. The following auxdata block forces the name to "orion_nand",
so the clk framework finds it and keeps required clocks enabled.
