arm64: dts: imx943: Correct PCIe outbound address space configuration
Fix the PCIe outbound memory ranges for both pcie1 controllers on i.MX943.
The memory window size was incorrectly set to 256MB during initial
bring-up, but the hardware supports up to 4GB of outbound address space
per controller.
Additionally, the ECAM region cannot be mapped as I/O space. Use a
memory-mapped region for I/O space instead, and relocate the 1MB I/O
region to immediately follow the memory region at offset 0xf0000000
within each window.
Update the outbound address space layout per controller as follows:
- 3.5GB 64-bit prefetchable memory
- 256MB 32-bit non-prefetchable memory
- 1MB I/O
