Subject: [PATCH] Add pulseio support for odroidc4

- added libgpiod_pulsein binary build on odroidc4
- added libgpiod_pulsein binary as package_data
- added extra check to verify if i2c is available
- added PulseIn to meson_g12_common that takes Pin instance
  and update pin id and chip name according to Pin
