All these uses assume it's always the id of fec device which is >= 0. However this is only true for non-DT case. When DT plays, pdev->id is always -1, which will break these pdev->id users. Instead of fixing all these users one by one, this patch introduces a new member 'dev_id' to 'struct fec_enet_private' for holding the correct fec device id, and replaces all the existing uses of pdev->id with this dev_id.

Clean it up a bit so we allow the logic to fail down to -ENODEV at the end of the if/else ladder, rather than using ifdefs to repeat the same failure code over and over. Also, remove the support for the auto-configuration. I'm not aware of anyone using it, and it ends up using the bus mutex before it's been initialized.

SoCs sometimes have a PCI host controller and there this code will not be executed, but there are some old SoCs with an PCI controller in client mode around and ssb_pcicore_fix_sprom_core_index() should not be called on these devices too. The PCI controller on these devices are unused, but without this fix it results in an Data bus error when it gets initialized.
