ieee1394: ohci1394: fix initialization if built non-modular

Initialization of ohci1394 was broken according to one reporter if the
driver was statically linked, i.e. not built as loadable module. Dmesg:

PCI: Device 0000:02:07.0 not available because of resource collisions
ohci1394: Failed to enable OHCI hardware.

This was reported for a Toshiba Satellite 5100-503. The cause is commit
8df4083c5291b3647e0381d3c69ab2196f5dd3b7 in Linux 2.6.19-rc1 which only
served purposes of early remote debugging via FireWire. This
functionality is better provided by the currently out-of-tree driver
ohci1394_earlyinit. Reversal of the commit was OK'd by Andi Kleen.
