firewire: nosy: misc cleanups

Extend copyright note to 2007, c.f. Kristian's git log.

Includes:
  - replace some <asm/*.h> by <linux/*.h>
  - add required indirectly included <linux/spinlock.h>
  - order alphabetically

Coding style related changes:
  - change to utf8
  - normalize whitespace
  - normalize comment style
  - remove usages of __FUNCTION__
  - remove an unnecessary cast from void *

Const and static declarations:
  - driver_name is not const in pci_driver.name, drop const qualifier
  - driver_name can be taken from KBUILD_MODNAME
  - the global variable minors[] can and should be static
  - constify struct file_operations instance

Data types:
  - Remove unused struct member struct packet.code.  struct packet is
    only used for driver-internal bookkeeping; it does not appear on the
    wire or in DMA programs or the userspace ABI.  Hence the unused
    member .code can be removed without worries.

Preprocessor macros:
  - unroll a preprocessor macro that containd a return
  - use list_for_each_entry

Printk:
  - add missing terminating \n in some format strings
