meta-ibm: acx22: new YAML dependency scheme

A prior patch added a new recipe acx22-yaml-config to provide all the
YAML configuration for ACx22 systems.  This patch switches the layer to
that recipe by setting EXTRA_OECONF and DEPENDS as appropriate in the
required bbappends.

With this switch, a number of recipes and their provided YAML are now
dead metadata, so remove those.
