Document manifest change to use groups

Rather than the manifest repo containing separate default.xml and
default-notools.xml, there is now a single default.xml, and one may use
repo init's -g option to cut down what gets synced. Update the README
to document this.

-There are two separate repo manifests for this project. Use repo's -m option
-to specify which you want. Valid values are default.xml (all required
-dependencies) and default-notools.xml (excludes the source to potentially
-distro-packaged utilities cbootimage, tegrarcm, dtc).
+The manifest includes the source to potentially distro-packaged utilities
+such as cbootimage and tegrarcm, and U-Boot itself. If you already have the
+pre-requisite tools installed, you may not want to download their source.
+Similarly, if you already build U-Boot yourself, you may not want another
+copy of the U-Boot source tree. You can request that repo not download
+those source trees using the -g option to repo init. For example:
+
+# Exclude just the pre-requisite tools:
+repo init -u ... -g default,-notools
+
+# Only include the bare minimum
+repo init -u ... -g default,-notools,-bootloader
