pci: msc01: Use PCI_CONF1_ADDRESS() macro

Browse source 
PCI msc01 driver uses standard format of Config Address for PCI
Configuration Mechanism #1 but with cleared Enable bit.

So use new U-Boot macro PCI_CONF1_ADDRESS() with clearing PCI_CONF1_ENABLE
bit and remove old custom driver address macros.
