PWM measurement

Module XML file: pwm_meas.xml

PWM input measurement mcu periph access and init wrapper for other modules.

  For LPC21xx on the TWOG:
  - INPUT CAPTURE CAP0.3 on P0.29 (TWOG ADC5, 5V to 3.3V voltage divider)
  - INPUT CAPTURE CAP0.0 on P0.30 (TWOG ADC4, no voltage divider)

  Currently only available on LPC21xx arch
