DE2 in A64 has clock control unit and behavior is same like H3/H5, so reuse the same in A64.

The A64 was released before the H5, so that should be the other way around.

So it turns out we don't need the SRAM to access the CCU driver?
As now U-Boot claims SRAM, people may forget thus :-(
I've sent few mails about how we represent de2 with sram_c [1] but none response after. Can I get further inputs so-that we can include sram_c in proper manner.

Please wait for the SRAMC driver sent by Chen-Yu (and commited by me) and the DE2 bus driver pending for the SRAMC part.
