[netdrvr tc35815] many fixes, major and minor 

* s/int/unsigned long/ for 'flags' arg passed to spin_lock_irqsave
* s/unsigned int/unsigned long/ for I/O port addresses
* no need to prevent tc35815_probe from being called multiple times...
  PCI layer will do things properly for us.
* call pci_enable_device before accessing hardware, before obtaining
  irq number, and before obtaining I/O port addresses.
* remove bogus 'if (pdev)' check in PCI API ->probe function
* call SET_M0DULE_OWNER, remove MOD_{INC,DEC}_USE_COUNT
* (cleanup) don't bother casting from a void*
* (cleanup) mark debugging function with #if 0, just like the caller
* Fix many printk statements to indicate that tc_readl() returns
  a long, not an int.
* (cleanup) remove unused tc35815_proc_info function
