The AKEBONO config has various selects under it, including some with
user-selectable dependencies, which means those dependencies can be
disabled. This leads to warnings from Kconfig.
This can be seen with eg:
$ make allnoconfig
$ ./scripts/config --file build~/.config -k -e CONFIG_44x -k -e CONFIG_PPC_47x -e CONFIG_AKEBONO
$ make olddefconfig
WARNING: unmet direct dependencies detected for ATA

The problem is that AKEBONO is using select to enable things that are
not true dependencies, but rather things you probably want enabled in
an AKEBONO kernel. That is what a defconfig is for.
So drop those selects and instead move those symbols into the
defconfig. This fixes all the kconfig warnings, and the result of make
44x/akebono_defconfig is the same before and after the patch.
