Added config for new Red Brick 70A v3 ESC

[ahalekelly]

Hobbyking changed their board again, and just swapped CpFET and BpFET, on pins PC3 and PC5. Credit to Kyle Singer for figuring this out.

Confirmed working.

I had a non working RB70A loaded with RB70a2, I was wondering what was wrong so I probed the board out and figured out the problem, tested then came to submit a PR and found this :) oops.

Just in case anyone else is googling for this, numbers silkscreened on the board are 500403-1040-02 and 16 15 GO123

Thanks!

Also found on a RB 125A ESC with the control board marked "500201-1032-02".

FYI, here's the Makefile and include changes to go with the board inc addition. I didn't want to confuse by sending a new PR with everything.
