firewire: core: prefix log messages with card name

Associate all log messages from firewire-core with the respective card
because some people have more than one card.  E.g.
    firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
    firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
    firewire_core: created device fw0: GUID 0814438400000389, S800
    firewire_core: phy config: new root=ffc1, gap_count=5
    firewire_core: created device fw1: GUID 0814438400000388, S800
    firewire_core: created device fw2: GUID 0001d202e06800d1, S800
turns into
    firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
    firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
    firewire_core 0000:04:00.0: created device fw0: GUID 0814438400000389, S800
    firewire_core 0000:04:00.0: phy config: new root=ffc1, gap_count=5
    firewire_core 0000:05:00.0: created device fw1: GUID 0814438400000388, S800
    firewire_core 0000:04:00.0: created device fw2: GUID 0001d202e06800d1, S800

This increases the module size slightly; to keep this in check, turn the
former printk wrapper macros into functions.  Their implementation is
largely copied from driver core's dev_printk counterparts.
