Add new target CORVON405V2

[holydust]

Dear iNav Developers,
I am writing to introduce our company Feikong Technology Co., Ltd. We specialize in designing and manufacturing hardware components for drones under our brand name, CORVON.
we have tested our flight controller "CORVON405V2" well, hope could add it to iNav supported hardware.
Looking forward to contributing to iNav.
Best regards
Holydust

DSHOT verified on S1-S7. Servo / pwm only on S8- S10.
For the UARTS, only UART1 did not pass.

Confirming @holydust there is no pinio to turn the VTX power off or any other purpose?

The SD card for blackbox is currently not working. Ity might be worth double-checking the SPI pins.

Thanks
Yes, VTX power is always on, we didn't set pinio to control it.

After I wrote the comment about the blackbox SPI, I realized the Alternate Function may need to be set for the SPI pins. Something similar to this example from a different board:

Testing has completed - everything is confirmed. The blackbox SD card was a bit wonky, but that's likely because of my card or an INAV issue.
