arm64: tegra: Fix Prefetchable aperture ranges of Tegra234 PCIe controllers
commit edf408b946d3 ("PCI: dwc: Validate iATU outbound mappings against
hardware constraints") exposes an issue with the existing partitioning of
the aperture space where the Prefetchable apertures of controllers
C5, C7 and C9 in Tegra234 cross the 32GB boundary hardware constraint.
This patch makes sure that the Prefetchable region doesn't spill over
the 32GB boundary.
Fixes: ec142c44b026 ("arm64: tegra: Add P2U and PCIe controller nodes to Tegra234 DT")
