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).
