Subject: [PATCH v2] PCI: tegra: Fix afi_pex2_ctrl reg offset for Tegra30

Fix AFI_PEX2_CTRL reg offset for Tegra30 by moving it from the Tegra20
SoC struct where it erroneously got added. This fixes the AFI_PEX2_CTRL
reg offset being uninitialised subsequently failing to bring up the
third PCIe port.

Fixes: adb2653b3d2e ("PCI: tegra: Add AFI_PEX2_CTRL reg offset as part of SoC struct")

Changes in v2:
- Fix recipient list concerning CC: and To: lines as suggested by
Thierry.
- Fix subject line and commit message to adhere to standard formatting
rules as suggested by Thierry.
- Add Thierry's Acked-by tag.
- Add standard Fixes tag as suggested by Andrew.
