PCI: tegra194: Use DWC IP core version

Browse Source 
Tegra194 PCIe driver used custom version numbers to detect Tegra194 and
Tegra234 IPs. With version detect logic added, version check results in
mismatch warnings:

  tegra194-pcie 14100000.pcie: Versions don't match (0000562a != 3536322a)

Use HW version numbers which match to PORT_LOGIC.PCIE_VERSION_OFF in
Tegra194 driver to avoid these kernel warnings.
