I haven't found a use yet (ie. pxa27x has no use for it, while for pxa3xx and
pxa25x I don't know yet).
I had put that here for a "CKEN" type clock which would be declared, but hidden
from device-tree. That's the meaning of "CLK_NONE", hidden from DT.

I can remove it if you think that there is no pxaXXX which needs this functionality.

Yes it is. pxa_clocks[0] is never filled by any clock.

Cheers.
