cpu/amd/geode_lx: Drop support
These chips are still using LATE_CBMEM which was agreed upon to
be removed after release 4.7. It is now more than 1 year later
and they still linger around.
The work and review to bring this code up to date can happen on
the 4.9 branch and then squashed together and merged back into
mainline when done.
