WCN3990 is a 37-bit target but can address memory range only upto 35 bits. The 36th bit is used to control the smmu/iommu translation and the 37th bit is used by the internal bus masters to access the wifi subsystem internal SRAM. With the DMA mask set to 37i-bit, the host driver can get 37-bit dma address, which leads to incorrect address access in the target. Hence the host driver can used addresses upto 35-bit for WCN3990. Fix the dma mask for wcn3990 to 35-bit, instead of 37-bit.
