There are timers with a 64-bit counter value but current timer uclass driver assumes a 32-bit one. Introduce a device tree property "counter-64bit", and modify timer_get_count() in the timer uclass driver to handle the 32-bit/64-bit conversion automatically.

Thanks a lot. I tested patches [1-4] on nios2 boards with "ut time" and "sleep". It works fine.
I would suggest that we do not need the additional "counter-64bit" property by requiring the timer always return 64 bits count. We can provide an inline func to do the 32/64 conversion for all 32 bits timers.
