Only write pwm_enable if it has an env var

Some device drivers don't need pwmX_enable written, so
only do it if an environment variable is present that
contains the value to write.

The environment variable is specified in the conf file
along with the other enviroment variables and would look like:
ENABLE_fan1 = "2"
