Using the newlib's printing functions without floating point support in order
to reduce the overall binary size. This allows to free up around 15kB of space
in the .text section.
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.

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.

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.

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.
