[linux-yocto] [PATCH] intel_pwm: refactor and use the feature fragment

[california.l.sullivan at intel.com]

From: California Sullivan <california.l.sullivan at intel.com>

Configure PWMs on Intel platforms as modules and add it to intel-common-drivers.
Remove PWM configurations from baytrail.cfg since its enabled elsewhere.
