Initialize Bluetooth chip in HCI_H4 mode and provide a firmware binary
with the IBS and DEEP_SLEEP mode disabled by default. Also this firmware
enables an internal clock required to maintain the system on low power modes.

The Digi vendor kernel uses a dedicated HCI UART driver with support for
In-Band Sleep (IBS). This driver, when used with a QCA vendor ROME plugin
for hciattach, is able to upload a new firmware version to the Bluetooth
chipset, as well as set the MAC address directly on the firmware.
Mainline BSP uses the HCI H4 driver instead and the "qualcomm" hciattach
plugin which is not able to upload firmware to the QCA6564 chipset.
As such, when using mainline the chipset uses the ROM firmware and the
bluetooth init script has been adapted accordingly.

Rarely the bluetooth firmware is not loaded properly and causes
errors in the configuration steps. This verification makes sure
the firmware was loaded and is functional, if not we start the
retry mechanism with the default baudrate to avoid the firmware
corruption in the upload process.

Bash v4.4 or higher warns when discarding NULL bytes in command substitution
