clocksource/drivers/fttmr010: Fix aspeed-2500 initialization
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.
