arm: kirkwood: Move configuration of some commands to _defconfig files

For Marvell plugs, move the configuration of DHCP, NAND/SF, PING
and USB commands, and HUSH_PARSER into the _defconfig file, rather
than the include/configs/*plug.h files.

This avoids compiler warnings of duplicate definitions if the
option is selected in the .config, but also defined in the
include/configs/*plug.h file.
