[PATCH BlueZ v2 1/9] lib: Add HDT definitions

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Add the socket API needed for the LE HDT PHY:

- BT_PHY bits for the HDT2, HDT3, HDT4, HDT6 and HDT7.5 rates in each
  direction, with the existing bits converted to BIT() for consistency
- bt_security.mic_len to request and read the MIC length of a link
- struct bt_iso_qos_v2, which adds the rates field to the ISO QoS
  passed with BT_ISO_QOS
