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.

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.

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.
TG-553
Rewritten the conversion law from ADC measurement in mV and normalized
0-255 output, adding a linearization if the pseudo-logarithmic output
curve of the potentiometer.

Stub drivers provide a safe default implementation of the OpenRTX interface
APIs and can be used both as a starting point to implement the actual drivers
and to allow compiling binary images without needing to provide an actual
implementation first.
Given that each radio driver loads its calibration data when initializing
and that the radio driver is strongly platform-specific, there is no strong
need for an intermediate redirection layer through the platform API.
Changed the hwInfo variable to static const in all the platformw where
the information are not loaded from NVM. Doing so puts the variable in
.rodata section and spares a tiny amount of RAM and FLASH.
