[PATCH] net: phy: bcm54140: Make a bunch of functions static

[ChenTao]

Fix the following warning:

drivers/net/phy/bcm54140.c:663:5: warning:
symbol 'bcm54140_did_interrupt' was not declared. Should it be static?
drivers/net/phy/bcm54140.c:672:5: warning:
symbol 'bcm54140_ack_intr' was not declared. Should it be static?
drivers/net/phy/bcm54140.c:684:5: warning:
symbol 'bcm54140_config_intr' was not declared. Should it be static?
