Subject: [PATCH v2 05/34] ARM: tegra: apalis_t30: annotate/clean-up pcie controller/port nodes

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Annotate PCIe port nodes and clean-up PCIe controller/port status' with
respect to carrier board vs. module level device trees. As port 3
connects to the on-module Gigabit Ethernet MACPHY it is always enabled
together with the PCIe controller itself.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Changes in v2:
- Clean-up PCIe controller/port status' as well.
