It would be better to split them into separate files. The platform driver is now called pwm-lpss-platform. Thus, previously set CONFIG_PWM_LPSS=m is not enough to build it. But we are on the safe side since it seems no one from outside Intel is using it for now. While here, move to use macros module_pci_driver() and module_platform_driver().

LP3943 can be used as a PWM generator, up to 2 channels. * Two PWM generators supported * Supported PWM operations request, free, config, enable and disable * Pin assignment A driver data, 'pin_used' is checked when a PWM is requested. If the output pin is already assigned, then returns as failure. If the pin is available, 'pin_used' is set. When the PWM is not used anymore, then it is cleared. It is defined as unsigned long type for atomic bit operation APIs, but only LSB 16bits are used because LP3943 has 16 outputs.
