Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc state for SPL only") it has been impossible to set clock defaults before relocation. This is annoying on boards without SPL, since there is no way to set clock defaults before U-Boot proper. In particular, the aisram rate must be changed before relocation on the K210, since U-Boot will hang if we try and change the rate while we are using aisram.
To get around this, (ab)use the stage parameter to force setting defaults, even if they would be otherwise posponed for later. A device tree property was decided against because of the concerns in the original commit thread about the overhead of repeatedly parsing the device tree.

But I think this should be an enum.
