Currently the pl022 driver expects clocks, and dts provide them, yet the binding does not mention clocks at all. This patch adds a description of the clocks, "apb_pclk" (as required by the primecell binding) and "sspclk" for the pl022 itself. The "sspclk" name was chosen to match the official documentation, as currently a variety of names are used in its place; it is expected that any operating system supporting these can continue to do so in the absence of an "sspclk" entry.
