The recent changes made the fttmr010 to be more generic and support different
timers with a very few differences like moxart or aspeed.

The aspeed timer uses a countdown and there is a test against the aspeed2400
compatible string to set a flag.

With the previous patch, we added the aspeed2500 compatible string but without
taking care of setting the countdown flag.

Fix this by specifiying a init function and pass the aspeed flag to a common
init function.

Sorry for the mistake :(
I don't have the Aspeed systems myself but I bet this works.

Thanks everyone.

Andrew, I think you had to fix up the clock device tree entries in the
Aspeed device tree. Can you please send me a patch for that?

Cheers,

Joel
