These patches enable PCI Express support on Tegra2.
The implementation is based on original NVidia code from (1), but it
is heavily reworked to avoid custom PCI enumeration and make the code
more Linux friendly.
This implementation assumes that the PCIe subsystem is fully powered
and ungated by the bootloader.
