Synopsys DesignWare core based PCIe controllers in Tegra 194 SoC interface
with Universal PHY (UPHY) module through a PIPE2UPHY (P2U) module.
For each PCIe lane of a controller, there is a P2U unit instantiated at
hardware level. This driver provides support for the programming required
for each P2U that is going to be used for a PCIe controller.

ARCH_TEGRA is a bit too much, ARCH_TEGRA_194_SOC should fit better here.

Ok. I'll take care of it in the next patch series.
