This patch brings support for the JZ4780 efuse. Currently it only exposes a read only access to the entire 8K bits efuse memory and the ethernet mac address for the davicom dm9000 chip on the CI20 board.
It also changes the nemc reg range to avoid overlap.

This is wrong, the real size of the register area is 1x15c.

As explained in my response to the other patch, 'clock-names' can go away.
