viafb: select HW scaling on VX900 for IGA2
commit 050f0e02c8dc38b2b4f2df345ac760d22ca5c7ba upstream. VX900 can do hardware scaling for both IGAs in contrast to previous hardware which could do it only for IGA2. This patch ensures that we set the parameter for IGA2 and not for IGA1. This fixes hardware scaling on VX900 until we have the infrastructure to support it for both IGAs.
