Any chance we could rename and list them as just BananaPi xxx?

When the BananaPi-R2 was mainlined, I asked the submitter to ask them
whether the vendor was Sinovoip or Bananapi, and they (Bananapi team)
said it was Bananapi.

We managed to convert a few (the BPI-M2+), but most still carry the
Sinovoip name.
