This includes simple upgrade (downgrade) capability in the MCU support
package. If hash of firmware installed on the MCU doesn't match the one
available on host's local file system, it will get upgraded.

In case of some types of MCU firmware, additional tools, daemons, kernel
drivers, etc. are required on the host side. For example, for Bluetooth
HCI controller, at least kernel module and BlueZ should be included.
This adds a simple recipe which generates dependencies list per firmware
type/name and for existing 'hci_usb' and 'hci_uart', selects 3 packages:
'bluez-daemon', 'kmod-bluetooth' and 'kmod-crypto-user'.
Kernel crypto interface in user space has to be also included because
the BlueZ isn't able to create static address for LE-only controller
without it, which results in no registration of new BT interface:
bluetoothd[668]: src/adapter.c:get_static_addr() Failed to open crypto
bluetoothd[668]: No Bluetooth address for index 0

This adds Zephyr firmware builds from custom git branch based on the
latest's upstream branch name 'main': 'main__mcu-on-wifi-boards'.

The new 'mcu-firmware' package will provide binary firmware dedicated
for MCU embedded on Wi-Fi boards (and also standalone, e.g. USB based),
supported by the OpenWrt/OpenWiFi projects. Currently, only Zephyr RTOS
based sample firmware ('BLE HCI controller' and 'hello world') files are
provided, for Wi-Fi boards and one standalone development module, listed
below:
- CIG WF-196 (Nordic nRF52833, UART bus)
- EdgeCore EAP102 (Nordic nRF52840, USB bus)
- Nordic nRF52840 Dongle (Nordic nRF52840, USB bus)
Different firmware types planned in future include Nordic's nRF Connect
SDK, OpenThread and others.
The Zephyr based firmware comes from a custom fork available in GitLab:
'https://gitlab.com/pepe2k/zephyr' (firmware in this package were built
from a v3.3.0 release based branch 'zephyr-v3.3.x__mcu-on-wifi-boards').
MCU firmware from this package is compatible only with OpenWrt/OpenWiFi
generic MCU support stack which, among others, assumes availability of
compatible bootloader (MCUboot is currently the only one supported) and
e.g. multiple firmware slots. MCUboot fork development takes part in git
repository hosted in GitLab: 'https://gitlab.com/pepe2k/mcuboot/'.

This adds support for creating initial MCU configuration with use of
'uci-defaults' in a same was as for example 'uboot-envtools' package.

On device running OpenWiFi with uCentral, additional copy of the initial
UCI configuration will be generated in '/etc/config-shadow/'. As part of
the MCU configuration is done during runtime, after the 'config-shadow'
is created, we should update it as well to keep everything in sync.

This introduces new package 'mcu' which is a collection of shell based
scripts used as glue code for generic MCU configuration and management.
The scripts are responsible for communicating with embedded MCU running
compatible MCUboot bootloader version over MCUmgr/SMP protocol.
The communication is realized based on usage of the introduced earlier
dedicated CLI tool called 'umcumgr.
The most important function of this package is a simple MCU's firmware
management (checking firmware available in the MCU's internal flash,
uploading new and selecting active on multi-firmware slot capable MCU).
This solution requires MCU running modified version of MCUboot,
available in GitLab: https://gitlab.com/pepe2k/mcuboot

The 'umcumgr' is a simple command line tool for MCU firmware management
over MCUmgr/SMP protocol. It will be used together with MCUboot running
on the on-board (or external, e.g. in form of a dongle) MCU.
While at it, add also dedicated 'mcu.yml' profile file.
