Fixed error in compuation of values for AT1846S frequency registers
causing the output frequency to have an effective resolution of 1kHz
instead of 62.5Hz.
T-TWR Plus target now produces images in UF2 format.
This format is compatible with bootloaders such as tinyuf2, and future
releases of the hardware will come pre-flashed with tinyuf2, thus
flashing them will not requires any other dependency than the uf2 file
itself.

Enabled 10 second long press emergency shutdown PMU function to be able
to reset the radio even when OpenRTX is freezed, without the need of
pulling out and back in the battery.

On LILYGO T-TWR Plus the squelch was being controlled by AT1846s,
resulting in the squelch bar setting being completely ignored. Now we
are introducing the support for a new command of sa8x8-fw called
AT+AUDIO that controls the muting or unmuting of the speaker power
amplifier, enabling us to:
1. Disable AT1846s embedded squelch
2. Enable OpeRTX squelch
Also fixed a bug where the sa8x8-fw version was incorrectly checked.
AT+AUDIO requires sa8x8-fw version v1.3.0.r1, bumped version check in
OpenRTX.

This will swap the first extended callsign with the source callsign
if there is extended callsign data.
This allows to always store the true source in the M17_src variable
See #188
Add west manifest contributed by edgetriggered to allow automated
cloning of the correst Zephyr revision.
Now codec2 dependency is enabled also for T-TWR build, enabling to build
it from scratch without first building a Miosix target.
Enabled non-cross build to use codec2 compiled sources.
We check if the battery is below minimum and, if so, assume that the charge
is 0%. This to prevent an underflow which would result in the function
returing a 100% charge level.
TODO: the include fixes can be probably refactored by including the
correct zephyr directories, as include/zephyr/posix/pthread.h should
already bringing in those header files.
TG-553
Replaced KEY_F7 and KEY_F8 with KEY_VOLUP and KEY_VOLDOWN.
Remapped the T-TWR Plus volume up and down keys to those, fixing a bug
in the pmu key detection where the wrong active edge was selected.
Adapt soft volume code for the UV3x0 to control code in the T-TWR Plus
by acting on the AT1846s Rx gain.
For target T-TWR Plus bound long press of KEY_VOLDOWN to macro menu open.
Unbound KNOB_LEFT and KNOB_RIGHT to squelch control and bound
instead KEY_VOLUP and KEY_VOLDOWN.

T-TWR Plus appears to have sever voltage drops during normal operation,
therefore we cannot use OpenRTX's low voltage warning screen on this
radio.
TG-553
The bug was due to an uninitialized memory being used to configure the
RTX thread, that disabled Tx in a random way by randomly set the
txDisable field.
TG-553
A proper baseband reset is now issued at each startup. Now OpenRTX check
for SA868 responsiveness before proceeding with radio initialization,
eliminating unstable behaviour at boot.
TG-553
Enabled AT+TURBO command on SA868 that switches the baud rate of the
serial communication from 9600 to 115200 to get a more responsive
baseband. Bumped up the required baseband firmware version to
v1.1.0.r20.
TG-553
Modified keyboard mapping to enable macro menu, interface is still
broken as the T-TWR Plus is missing a keyboard.
Now the volume down key, mapped as the MONI button can be also used to
set the squelch level.
TG-553
Enabled Tx capability on T-TWR Plus.
Since Tx requires the SA8x8 to disable the Rx stage, we check that at
least firmware v.1.1.0.r14 is present on the baseband, otherwise we
don't initialize the radio.
TG-553
Add support for initializing SA868 and querying its firmware version,
created a new instance of the AT1846S class that leverages the SA8x8
serial connection as an i2c implementation.
Rx works! In the sense that the RSSI bar behaves as expected, still no
audio.

Begin implementing PMU, now successfully read and write registers, need
to implement button functionality, battery voltage readout, charge
detection etc.
TG-553
Zephyr already provides button support based on gpios. We are mapping
Zephyr keycodes to OpenRTX therefore future targets will only need to
configure their devicetrees to have button support.
Rotary encoder readout leverages the hardware pulse counter. PTT in
this device is also bound to KEY_ESC, that matched the behaviour
observed in many commercial radios.
