px4_fmu-v4pro Fix PX4IO firmware upgrade

[davids5]

The PX4IO was responding but the RX DMA stay borke

This fixes USART6 RX DMA Assignment

Thanks David. I'd like to take this as an opportunity to get the test rack into a state where it can actually catch trivial things like this. All boards on the test rack routinely get stuck in a state where the px4io is unrecoverable.

Still failing here. http://ci.px4.io:8080/blue/organizations/jenkins/PX4_misc%2FFirmware-hardware/detail/master_px4pro_px4io_fix/1/pipeline/498

I'm also still trying to figure out why the redefinition wasn't a compile time warning.

@dagar

Would you please send me the image from 0 to 0xffff as a bin file extracted from the PX4IO on the V4PRO of the test rack?
