memory: tegra: Add dummy implementation on Tegra194
With the introduction of commit 9365bf006f53 ("PCI: tegra194: Add
interconnect support in Tegra234"), the PCI driver on Tegra194 and later
requires an interconnect provider. However, a provider is currently only
exposed on Tegra234 and this causes PCI on Tegra194 to defer probe
indefinitely.
Fix this by adding a dummy implementation on Tegra194. This allows nodes
to be provided to interconnect consumers, but doesn't do any bandwidth
accounting or frequency scaling.
Fixes: 9365bf006f53 ("PCI: tegra194: Add interconnect support in Tegra234")
