drivers/net/skfp: fix sparse warning: Should it be static?

Impact: Move function declarations to header file.

Fix this sparse warnings:
drivers/net/skfp/cfm.c:146:6: warning: symbol 'all_selection_criteria' was not declared. Should it be static?
drivers/net/skfp/drvfbi.c:186:6: warning: symbol 'mac1_irq' was not declared. Should it be static?
drivers/net/skfp/drvfbi.c:284:6: warning: symbol 'read_address' was not declared. Should it be static?
drivers/net/skfp/drvfbi.c:323:6: warning: symbol 'init_board' was not declared. Should it be static?
drivers/net/skfp/fplustm.c:72:24: warning: symbol 'fddi_broadcast' was not declared. Should it be static?
drivers/net/skfp/fplustm.c:679:6: warning: symbol 'mac2_irq' was not declared. Should it be static?
drivers/net/skfp/fplustm.c:805:6: warning: symbol 'mac3_irq' was not declared. Should it be static?
drivers/net/skfp/fplustm.c:856:5: warning: symbol 'init_fplus' was not declared. Should it be static?
drivers/net/skfp/pcmplc.c:404:6: warning: symbol 'init_plc' was not declared. Should it be static?
drivers/net/skfp/pcmplc.c:1592:5: warning: symbol 'pcm_status_twisted' was not declared. Should it be static?
drivers/net/skfp/smtinit.c:68:5: warning: symbol 'init_smt' was not declared. Should it be static?
