Correct a display port number extraction from EDID

While the display port number is embedded at the least 8-bit of EDID,
EVS uses only the least 4-bit so may cause conflicts between display
devices that have the same value in the least 4-bit.

This change fixes logics to use all 8-bit value as the port number and
updates config.json with the right display port numbers on the reference
platform.  Below command shows the port numbers display devices are
connected to:
$ adb shell lshal \
  debug android.hardware.automotive.evs@1.1::IEvsEnumerator/default \
  --list display
  Display devices available to EVS service:
    display port 136
    display port 130

Fix: 168931805
Test: Run above example and compare them against below command returns:
      $ adb shell dumpsys SurfaceFlinger --display-id
