gcc-6 reports the following error with -Werror=unused-const-variable.
drivers/net/wireless/broadcom/b43/phy_a.c:576:40: error:
'b43_phyops_a' defined but not used
Per Michael Büsch: "All a-phy code is usused", so remove phy_a.c
completely. Move the remaining Type-G initialization code into phy_g.c.

v2: Remove phy_a.c; move left-over code into phy_g.c
Remove now unused data structure

This actually is correctly called inita(), because there are A-phy parts
in the G-phy.
So I wasn't 100% correct saying that _all_ a-phy code is unused.
I'm Ok with moving that into the g-phy file though. But don't rename it.
