  ARM: Orion: SDIO: Add support for clk.
  ARM: Orion: NAND: Add support for clk, if there is one.
  ARM: Orion: EHCI: Add support for enabling clocks
  ARM: Orion: SATA: Add per channel clk/clkdev support.
  ARM: Orion: UART: Get the clock rate via clk_get_rate().
  ARM: Orion: WDT: Add clk/clkdev support
  ARM: Orion: Eth: Add clk/clkdev support.
  ARM: Orion: SPI: Add clk/clkdev support.
  ARM: Orion: Add clocks using the generic clk infrastructure.
