net: b44: always select CONFIG_FIXED_PHY

Browse Source 
When CONFIG_FIXED_PHY=m but CONFIG_B44=y, the kernel fails to link:

ld.lld: error: undefined symbol: fixed_phy_unregister
>>> referenced by b44.c
>>>               drivers/net/ethernet/broadcom/b44.o:(b44_remove_one) in archive vmlinux.a

ld.lld: error: undefined symbol: fixed_phy_register_100fd
>>> referenced by b44.c
>>>               drivers/net/ethernet/broadcom/b44.o:(b44_register_phy_one) in archive vmlinux.a

The fixed phy support is small enough that just always enabling it
for b44 is the simplest solution, and it avoids adding ugly #ifdef
checks.

Fixes: 10d2f15afb ("net: b44: register a fixed phy using fixed_phy_register_100fd if needed")

If you have a network (Ethernet) controller of this type, say Y
or M here.
