Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

TTC has three modes of operations. Timer, PWM and input counters.
There is already driver for timer under CADENCE_TTC_TIMER which is used for
ZynqMP R5 configuration.
This driver is targeting PWM which is for example configuration which can
be used for fan control.
The driver has been tested on Xilinx Kria SOM platform where fan is
connected to one PL pin. When TTC output is connected via EMIO to PL pin
TTC pwm can be configured and tested for example like this:
pwm config 0 0 10000 1200
pwm enable 0 0
pwm config 0 0 10000 1400
pwm config 0 0 10000 1600
