PCI: tegra194: Use DWC IP core version

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.
