Change base-address-setting parameter from force or force_via686a

to force_addr. It is now consistent with the bus PCI adapters
      that support base address setting (piix4, i801, viapro).
      Other benefit is that via686a_find can now return -ENODEV,
      and module will fail to load when base address is not set and
      parameter is not used.
