Enabling SMBus timeout in the capacitive touch sensor and not in the MCU would cause the CTS to reset and the MCU expecting the transaction to keep going, locking-up the device.
Timeout should be re-enabled when SMBus will be implemented.
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.

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.

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.

Use main screen bottom bar in mode screen
mode screen: Move frequency and channel name to center
Show S-meter without squelch bar for digital modes
Change S-meter for digital modes, add audio level meter
Print FM information in mode screen
Add mode screen fonts
Added: qdec, a header only quadrature encoder library
Added: EXTI15_10_IRQHandler to handle the encoder knob
Changed: platform_init() for the MD-UV380 now configures the EXTI15_10
interrupt.
Changed: platform_getChSelector now returns signed int8
Changed: size of settings_t.valid went from 6 to 7
Without this change, pressing the macro button crashes the radio, I
haven't investigated and I don't remember how I found that solution.
Changed: meson.build includes the qdec library
