[PATCH v4 0/2] regulator: get voltage & duty table from dts for st-pwm

[Chris Zhong]

get voltage & duty table from device tree might be better, other platforms can also use this
driver without any modify.
Tested on a rk3288 sdk board as logic voltage regulator.

Changes in v4:
Adviced by Doug Anderson
- improve kconfig
- add const for desc structure

Changes in v3:
Adviced by Doug Anderson
- Make Kconfig & Makefile alphabetical
- remove pwm_reg_period from pwm_regulator_data
- modify the calculation in pwm_regulator_set_voltage_sel
- add length validity check
Adviced by Doug Anderson
- update the Example

Changes in v2:
Adviced by Lee Jones
- rename the file
- remove all the prefix st_
- add depend on PWM in Kconfig
Adviced by Lee Jones
- rename the documentation
Adviced by Doug Anderson
- update the example
Adviced by Mark Rutland
- remove pwm-reg-period
