meta-ibm: move all meta-witherspoon metadata
The metadata common to all IBM systems is confusingly split between
meta-ibm and meta-witherspoon. Move everything to meta-ibm.
The meta-ibm README is re-written to more accurately reflect the scope
of the layer.
Allow the configuration samples (bblayers.conf.sample,
local.conf.sample) to be sourced from either meta-ibm or
meta-witherspoon until such a time that any workflows and tooling have
had the opportunity to move to meta-ibm.
(From meta-ibm rev: 6e05ef2e90b214eaf4e43ee7027bbbb1d8d09442)
