488ea234d5 adafruitms1438: fix a bug in PWM handling for DC motors
Eric Hubert reported a bug in that no matter what setting he used to
control the speed of a DC motor, it was always running at full speed.

There was a bug in the setMotorSpeed() method that did not clear the
'FullOn' bit in the register used for PWM, causing full power to be
applied all the time no matter the PWM duty cycle setting.

This patch corrects that issue.

5fac6e9811 adafruitms1438: Initial implementation
The library implements support for the Adafruit MotorShield 1438:
http://www.adafruit.com/products/1438

This shield supports 4 DC motors or 2 Stepper motors.

It makes use of the pca9685 UPM library, and therefore requires that
PR #123 and PR #134 are merged first:

PR 123: pkgconfig.in: allow a module to specify dependencies on
another module

PR 134: pca9685: Initial implementation
