powerpc/fsl: Setup PCI inbound window based on actual amount of memory
Previouslly we just always set the inbound window to 2G. This was
broken for systems with >2G. If a system has >=4G we will need
SWIOTLB support to handle that case.
We now allocate PCICSRBAR/PEXCSRBAR right below the lowest PCI outbound
address for MMIO or the 4G boundary (if the lowest PCI address is above
4G).
