I imagine Google was already using ASPEED BMCs in their x86 servers so they kept using it in OpenPOWER. There are some really specific things like PECI and VGA redirection that x86 BMCs need and AFAIK nothing besides ASPEED has those features.

I doubt IBM gave Google any thought in this matter. I'm pretty confident that it has a lot more to do with the way IBM does their market segmentation, and how that is related to hardware + software bundling and firmware. The ARM BMC fits in a HMC shaped hole.
