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

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.
