pci: tegra: Use PCI_CONF1_EXT_ADDRESS() macro

Browse source 
PCI tegra driver uses extended format of Config Address for PCI
Configuration Mechanism #1 but with cleared Enable bit.

So use new U-Boot macro PCI_CONF1_EXT_ADDRESS() with clearing
PCI_CONF1_ENABLE bit and remove old custom driver address function.
