Subject: [PATCH v4 1/5] pwm: Only descend into pwm directory when CONFIG_PWM is set

From: "Andrew F. Davis" <[email-masked]>
Date: Tue, 5 Dec 2017 13:44:52 -0600

When CONFIG_PWM is not set make will still descend into the pwm
directory but nothing will be built. This produces unneeded build
artifacts and messages in addition to slowing the build. Fix this here.
