ibm: Add a basic README

Most OE metadata repositories have a README.  Add a basic one for
meta-ibm.

meta-ibm never really had a clear direction of what it was supposed to
be, so give it one.

The top level meta-ibm will be a distro policy layer for IBM branded
servers.  Subtrees will be BSPs (and possibly additional distro policy)
for the components that make up the servers (BMCs and planars).

Note that meta-palmetto and meta-romulus are missing.  These are
OpenPOWER reference platforms and not IBM branded servers.  As such,
meta-palmetto and meta-romulus will be moved to meta-openpower.
