  4. dshot: add dshot driver 

    Supports all DShot modes, but no telemetry yet.
It includes the modes and capture configuration from FMU so that it serves
as drop-in replacement.

  18. dshot: reduce static buffer size 

    And handle failures of up_dshot_init().

On Omnibus: reduces memory usage if dshot is enabled by ~1.0KB.
The buffer is roughly 1KB in size.

  20. dshot: update timer generation before DMA request 

    This reloads the timer configuration before triggering DMA. Without that,
in rare cases, there were 17 bits sent instead of 16.
The 1. bit (1. pulse) was always wrong (too much), the rest of the bits
were the correct DShot packet that was meant to be sent.

  25. fmu-v5: add dshot support 

    But only on the first 4 FMU outputs, as the next ones conflict with px4io
serial dma (UART8_RX)

RX DMA is disabled on the GPS port as well (conflicts with TIM1).

  26. parameters: defer auto-saving to after disarming for flash-based params 

    This is especially important for DShot, that does not update when the CPU
stalls.
