mainboard/google/kahlee: Setting PSPP to BalanceHigh
Without IOMMU and PsppBalanceLow audio does not work and dma from sysmem to ACP sram gets stuck. We cannot have IOMMU enabled for ST as it causes a siginificant impact to performance and also can cause potential problems with ACP as ACP IP uses fixed address offset. Hence, setting to PsppBalanceHigh.
