Change the sha/aes/tdes compatibility string to match common
case for the at91sam9g45 family which is to keep the at91 prefix.

you keep the previous compatible in the driver too for backword compatiblity

No, as the consumer of the old compatibility string has never been sent to mainline (or even mailing-list) and as the "dma" property is not compatible with the one existing on our 3.6.9-based kernel.

So, anyway the DT has to be changed for a move from 3.6.9 => 3.10. As I do not want to bloat the DT forever, let's stick with this new compatibility string.

Bye,
