    arm926ejs: add noop implementation for dcache ops

breaks zmx25 booting with the following command:

tftpboot 0x82000000 foo.img; dcache on; bootm 0x82000000

It is stuck then in an endless loop after dcache is disabled before jumping to the OS.

------------------------------------------------
WARNING: cache operations are not implemented!
WARNING: disabling D-Cache now, you can re-enable itlater with 'dcache on' command
------------------------------------------------

Switching on dcache after the tftp worked without problems until this patch. I think this should be fixed before the release as it may have effects on other boards doing similar things.
