Bluetooth: add quirk disabling LE Read Transmit Power
commit d2f8114f9574509580a8506d2ef72e7e43d1a5bd upstream.
Some devices have a bug causing them to not work if they query
LE tx power on startup. Thus we add a quirk in order to not query it
and default min/max tx power values to HCI_TX_POWER_INVALID.
