regulator: pwm-regulator: Remove obsoleted property 

In "[3d7ef30] regulator: pwm-regulator: Simplify voltage to duty-cycle
call" we stopped using max_duty_cycle, so we can retire it from device
data and DT.

There is no need to deprecate this property, as it hasn't hit Mainline
yet.

@ -29,15 +29,14 @@ Required properties:
- pwms: PWM specification (See: ../pwm/pwm.txt)
One of these must be provided:
Only required for Voltage Table Mode:
- voltage-table: Voltage and Duty-Cycle table consisting of 2 cells
First cell is voltage in microvolts (uV)
Second cell is duty-cycle in percent (%)
- max-duty-cycle: Maximum Duty-Cycle value -- this will normally be
255 (0xff) for an 8 bit PWM device
If both are provided, the current default is voltage-table mode.
NB: To be clear, if voltage-table is provided, then the device will be used
in Voltage Table Mode. If no voltage-table is provided, then the device will
be used in Continuous Voltage Mode.
Any property defined as part of the core regulator binding can also be used.
