PCI: mediatek: Enlarge PCIe2AHB window size to support 4GB DRAM
The PCIE_AXI_WINDOW0 register defines the inbound window size for requests coming from PCI endpoints. Requests outside of this window will be treated as unsupported requests. Enlarge this window size from 2^31 to 2^33 to support a 8GB address space (which gives endpoints DMA access to full 4GB DRAM address range - physical DRAM starts at 0x40000000).
