I remember now why we do it in map_io().
Timers need clock support and they are up before machine_init() is called.

So, i believe i must have DT_MACHINE_START per SoC.

I will post V2 for 3xx DT support today, but can i have initial level of review
from you, so that i can fixup minor issues in V2 only?
