The board PCI setup code may control regulators that are required simply to bring up the PCI controller itself (or PLLs, IOs, ... it uses). Move the call to this function earlier so that all board-provided resources are ready early enough for everything to work.

It might be a good time to move Tegra to driver model for PCI.
