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.
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.

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.

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.

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
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.
