The primary consumer of the lpss pwm is the i915 kms driver, the i915 driver does not support get_pwm returning -EPROBE_DEFER and its init is very complex making this is almost impossible to fix.
This commit changes the PWM_LPSS Kconfig from a tristate to a bool, so that when the i915 driver loads the lpss pwm will be available avoiding the -EPROBE_DEFER issue. Note that this is identical to how the same problem was solved for the pwm-crc driver, which is used by the i915 driver on other platforms.
