This patch adds system clk ids definitions into dt-bindinds include dir (include/dt-bindings/clk/at91/'soc-name'/system-clk.h). These definitions will be used by dt definition to define and reference system clks.
As said earlier, I think that these definitions can be removed. We can stick with raw numbers and just document that we are using the offset of the coresponding bit in the register.
