sb,soc/amd: Drop OSFL method in ASL
Variable OSVR had a static value of 3 and OSFL() did not actually call _OSI or _OS methods. The conditional in HDA _INI method of OSVR is dropped and use of DMA NoSnoop attribute remains disabled to retain previous behaviour. For soc/amd/picasso a different decision was made in CB:40782 as HDA _INI method was just dropped and default configuration enables use of DMA NoSnoop attribute.
