[PATCH] ARM: dts: BCM5301X: drop extra AXI bus ranges that break PCIe

These addresses overlap with DRAM on BCM5301X/BCM470X SoCs, causing the OF
address translation code to route PCIe MMIO accesses through the AXI bus
space instead of directly to memory, breaking PCIe. Remove the extra
ranges to restore the original single-entry mapping that only covers the
AXI peripheral register space.
