[PATCH] net: dsa: mv88e6xxx: make unexported functions static

[Ben Dooks <ben.dooks@codethink.co.uk>]

The driver has a number of functions that are not exported or
declared elsewhere, so make them static to avoid the following
warnings from sparse:

drivers/net/dsa/mv88e6xxx.c:113:5: warning: symbol 'mv88e6xxx_reg_read' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:167:5: warning: symbol 'mv88e6xxx_reg_write' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:231:5: warning: symbol 'mv88e6xxx_set_addr' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:367:6: warning: symbol 'mv88e6xxx_ppu_state_init' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:3157:5: warning: symbol 'mv88e6xxx_phy_page_read' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:3169:5: warning: symbol 'mv88e6xxx_phy_page_write' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:3583:26: warning: symbol 'mv88e6xxx_switch_driver' was not declared. Should it be static?
drivers/net/dsa/mv88e6xxx.c:3621:5: warning: symbol 'mv88e6xxx_probe' was not declared. Should it be static?
