wifi: ipw2x00: Remove some unused functions

Functions write_nic_auto_inc_address() and write_nic_dword_auto_inc() are
defined in the ipw2100.c file, but not called elsewhere, so remove these
unused functions.

drivers/net/wireless/intel/ipw2x00/ipw2100.c:427:20: warning: unused function 'write_nic_dword_auto_inc'.
