From: Luiz Augusto von Dentz <redacted>

This adds the following record:

Service Name: AVRCP TG
Service RecHandle: 0x10002
Service Class ID List:
  "AV Remote Target" (0x110c)
Protocol Descriptor List:
  "L2CAP" (0x0100)
    PSM: 23
  "AVCTP" (0x0017)
    uint16: 0x103
Profile Descriptor List:
  "AV Remote" (0x110e)
    Version: 0x0100
