arm64: dts: ti: k3-am64-main: Switch to 64-bit address space for PCIe0

Browse Source 
The PCIe0 instance of PCIe in AM64 SoC supports:
1. 128 MB address region in the 32-bit address space
2. 4 GB address region in the 64-bit address space

The default configuration is that of a 128 MB address region in the
32-bit address space. While this might be sufficient for most use-cases,
it is insufficient for supporting use-cases which require larger address
spaces. Therefore, switch to using the 64-bit address space with a 4 GB
address region.
