meta-crownbay: update README
With the new emgd-driver-bin recipe, some of the extensive instructions on how to manually download and set up EMGD for the build are no longer necessary. Changes to reflect the new image names and a couple other minor cleanups are also included. Signed-off-by: Tom Zanussi <tom.zanussi@intel.com>
