Apply multicast offline workaround to hbrt path under opal

Multicast operations to non-pcbslave registers will return a
piberr of 'chiplet offline' if any chiplets (e.g. cores) are
offline.  To handle this we already ignore this scenario during
IPL.  This change adds some decode logic to convert opal
return codes into their equivalent piberr values.  With this
logic the workaround should trigger and avoid scom errors.

Resolves open-power/boston-openpower/#463
