c833697538 dm: timer: uclass: add timer init in uclass driver to add timer device
Adding timer init function in timer-uclass driver to create and
initialize the timer device on platforms where u-boot,dm-pre-reloc
is not used. Since there will be multiple timer devices in the
system, adding a tick-timer node in chosen node to know which
timer device to be used as tick timer in u-boot.

4932443d26 x86: Move i8254_init() to x86_cpu_init_f()
Right now i8254_init() is called from timer_init() in the tsc timer
driver. But actually i8254 and tsc are completely different things.
Since tsc timer has been converted to driver model, we should find
a new place that is appropriate for U-Boot to call i8254_init(),
which is now x86_cpu_init_f().

9ca07ebbac dm: timer: Support 64-bit counter
There are timers with a 64-bit counter value but current timer
uclass driver assumes a 32-bit one. Modify timer_get_count()
to ask timer driver to always return a 64-bit counter value,
and provide an inline helper function timer_conv_64() to handle
the 32-bit/64-bit conversion automatically.

f838f12452 timer: sandbox: Use device tree to pass the clock frequency
We should use device tree to pass the clock frequency of the timer
instead of hardcoded in the driver codes.

Since we have timer uclass to get clock frequency for us, remove
the custom version in the altera timer driver.

579eb5a0cc dm: timer: Implement pre_probe()
Every timer device needs to have a valid clock frequency and it
can be specified in the device tree. Use pre_probe() to get this
in the timer uclass driver.
