powerpc/85xx: Add SWIOTLB support to FSL boards Add the platform-specific code for enabling SWIOTLB if needed on P2020DS, MPC85xx DS, and MPC85xx MDS boards as they are capable of having >4G of memory. We determine if we need to enable swiotlb based on how much memory is in the board and if it exceeds 4G or what we can map via PCI inbound windows.
