Do not use hcitattach to reconfigure the baudrate but set it directly in the
Bluetooth FW file; this work arounds some synchronization problems when not
using HW flow control.

Add a couple of bluez patches: one for increasing the number of connection
showed with "hcitool con" command and remove "refresh" option in hcitool
help that is not supported.
The qca6564 chip can support more than 10 simultaneous BLE connections.

The power regulator connected to the qca6554 chip is always on, which causes
the Bluetooth part to not work correctly after a software-reset.
This commit asserts momentarily the BT_EN line during the start-up sequence
to reset the Bluetooth controller so that it is in a predictable state after a
reset.

The steps to set the bluetooth MAC address is send an specific hci command
and an hci reset, so the bluetooth interface need to be up in order to
configure it.
Additionally we have generalized the way to read the MAC address from the
device tree and removed some old code for getting the MAC address in
kernel version 2.

Add a software workaround to disable the HW flow control because the SOM
revision 3 (and older) has swapped the bluetooth TX and RX lines so we need
to operate in DTE mode which implies that the HW control lines are swapped.
This also implies reducing the baudrate to avoid the need for HW flow control.

Port the bluez5 qca6564 support based on 5.19 to the current version 5.33.
The ported version is based on qualcomm tag r110048.3.
