The Armada 370 has two gatable clocks for each PCIe interface, and we
want both of them to be enabled. We therefore make one of the two
clocks a child of the other, as we did for the sataX and sataXlnk
clocks on Armada XP.

Patches 5 - 8 applied to mvebu/pcie, with a dep on Sebastian's clock
rework and mvebu/of_pci.  Thanks for the head's up on the clk conflict.
My resolution should match yours.  Please let me know if it doesn't.

thx,

Jason.

As stated in the clk thread, I'm going to re-order this so pcie doesn't
depend on the clk series.

thx,

Jason.
