  This ID is included in upstream.

  [Impact]

   * Devices have goodix [27c6:63cc] fingerprint component will get
     supported.

   * This sru contains lots of fingerprint id which is not supported
  before, below is the comparison with impish -updates.

   * Elan:
     #impish: 0x0c4d

     Synaptics:
     #impish and focal does not have difference.

     Goodix:
     #0x609C, 0x639C, 0x63AC, 0x63BC and 0x6A94 are include in focal but not
     in impish

   * Add Synaptics fingerprint device to test in this SRU.
     VID: 06CB
     PID: 00DF

   * If user name is too short, fingerprint cannot enroll successfully
     https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/428

  [Test Plan]

   * Find a machine with this fingerprint device

   * set a very short user name such as "u".

   * Launch `settings` and enable `Fingerprint Login`

   * Enroll finger and then logout

   * Login system with enrolled finger

  [Where problems could occur]

   * A lot of fingerprint ids is supported in this version, we didn't test
     all combination.
