meta-amd: Add ipmi config, host and fru .bbappend files

This patch creates an empty DCMI sensors json file as EthanolX does not
define DCMI sensors. It also modifies phosphor-ipmi-fru and
phosphor-ipmi-host bitbake files to read the ipmi fru and sensors
configuration data from yaml files in configuration directory.
