yocto-bsp: clarify help with reference to meta-intel

The current yocto-bsp help assumes knowledge that the meta-intel layer
needs to be cloned before it's put into the BBLAYERS.  Avoid the
guesswork and state the details explicitly in the help.

Also, the shorter 'usage' string doesn't mention it at all; it would
help to at minimum mention it and refer the user to the detailed help.

Fixes [YOCTO #2330].
