Implement reading a clock duty cycle with new clock API function
clk_get_duty_cycle() and clock operation handle ::clk_get_duty_cycle.
When a clock does not provide the operation, it is assumed that the clock
has a 50% duty cycle.
Clock duty cycle information is used for example for some analog-digital
conversion peripheral. This new API function is also expected to be used
by SCMI clock service introduced in the SCMI specification v3.2 [1]
this allow to expose duty cycle service to SCMI clients.
