[PATCH v6 11/13] PCI: tegra194: Use HW version number

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

Tegra194 PCIe driver uses custom version number to detect Tegra194 and
Tegra234 IPs. With version detect logic added, version check results
in mismatch warnings.

Use HW version numbers in Tegra194 driver to avoid this kernel warnings.

Fixed version check to enable ecrc for Tegra194.
Existing 490A check is left intact in case any HW relying on existing check.

Fixes: a54e19073718 ("PCI: tegra194: Add Tegra234 PCIe support")
