mbed OS 5 target is currently missing wrappers around PwmOut and AnalogIn interface, which are part of the standard library of mbed OS. This commit adds them. Tested with mbed CI test shield. I've followed the coding style in jerryscript-mbed, rather than JerryScript coding style. JerryScript-DCO-1.0-Signed-off-by: Jan Jongboom janjongboom@gmail.com
