[PATCH] arm64: tegra: Bump CBB ranges property on Tegra194 and Tegra234

From: Thierry Reding <treding at nvidia.com>

Both Xavier (Tegra194) and Orin (Tegra234) support a 40-bit address map,
so bump the CBB ranges property to cover all of the 1 TiB address space.
This fixes an issue where some of the PCIe regions could not be remapped
because of they were outside the memory specified by the CBB's ranges
property.
