This series of patches do some enhancements and some bug fixes to the
Tegra194 PCIe platform driver like
- Fix Vendor-ID corruption
- Update DWC IP version
- Continue with uninitialization sequence even if parts fail
- Check return value of tegra_pcie_init_controller()
- Disable LTSSM during link's L2 entry
V5:
* Rebased the first patch in the series
* Dropped the second patch
* Added Tested-by and Acked-by for rest of the patches
V4:
* Added a new patch to address link-up issues with some of the cards
V3:
* Addressed Bjorn's review comments
* Split earlier patch-4 into two
- Continue with the uninitialization sequence even if some parts fail
- Check return value of tegra_pcie_init_controller() and exit accordingly
V2:
* Addressed Rob's comments. Changed 'Strongly Ordered' to 'nGnRnE'

Set the DesignWare IP version for Tegra194 to 0x490A. This would be used
by the DesigWare sub-system to do any version specific configuration
(Ex:- TD bit programming for ECRC).
