Add PWM driver to support PWM modules inside QCOM PMIC chips which are accessed through SPMI bus. Normally, there would be multiple PWM modules with adjacent address spaces present in one PMIC chip, and each PWM module has 0x100 size of address space. With this driver, a pwm_chip with multiple pwm_device individuals is created, and each pwm_device individual is corresponding to one PWM module.
