This patch fixes 5 style problems reported by checkpatch:

It also rebases and integrates changes sent by Ben Dooks [1]:

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?
