Fixed: PWM servo driver did not reset properly during initialization.
Passing debug flag from PWM to Adafruit_I2C.
Addition to fix in 4d92bf1: ending sleep of PCA9685 in PWM servo driver initialization.
Extended fix in 4d92bf1 to work if more than one PCA9685 is connected. In the old version any subsequent board initialization reset all previously initialized boards.
