[U-Boot] AT91 clock and timer cleanups

Dear Wolfgang Denk,

There is no at91 common header file that gets included BEFORE global_data.h,
unfortunately.

Maybe there is a misunderstanding here. I see three patches

1. introduce CONFIG_AT91SAM9_FAMILY to common.h

2. add an #ifdef CONFIG_AT91SAM9_FAMILY to global_data.h with the
required variables

3. change clock and timer.

2+3 combined in one patch? OK

And I bet, this must be a patch series ;)
