Add MMC layout
Add support for eMMC layout. The actual update of the image will
be handled by the BMC updater since the image file will be
packaged in a single tarball, but the eMMC still needs to have
some services to setup the host firmware mounts for the virtual
pnor configuration to use. Therefore the functions are empty.
