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.
