pci: tegra: call tegra_pcie_board_init() earlier
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.
