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)

+OpenEmbedded/Yocto/OpenBMC BSP layer for IBM systems
+====================================================
+
+This layer provides support for the BMC firmware on IBM POWER systems server
+products.
+
+```
+This layer depends on:
+
+URI: git://git.openembedded.org/openembedded-core
+layers: meta
+branch: master
+revision: HEAD
+
+URI: https://github.com/openbmc/meta-phosphor
+branch: master
+revision: HEAD
+
+URI: https://github.com/openbmc/meta-openpower
+branch: master
+revision: HEAD
+
+URI: https://github.com/openbmc/meta-aspeed
+branch: master
+revision: HEAD
+```
+
+The following systems are supported.
+
+Witherspoon, or AC922, is an IBM POWER9 two-socket, 2U Accelerated Compute
+Server with up to 6 NVIDIA Tesla GPUs. More information can be found
+[here](https://www.ibm.com/us-en/marketplace/power-systems-ac922).
+
+In addition to witherspoon, this layer contains additional machine
+configurations such as swift. The default machine target is witherspoon,
+so in order to build a different configuration, or to build witherspoon
+after building a different one, set the MACHINE environment to the desired
+configuration name (see the conf/machine/ subdirectory for available options):
+
+    export MACHINE=machine_configuration_name
+
+Then build:
+
+    bitbake obmc-phosphor-image
+
+Example:
+
+    export MACHINE=swift
+    bitbake obmc-phosphor-image
+    bitbake phosphor-logging
+
+    export MACHINE=witherspoon
+    bitbake obmc-phosphor-image
