create u-boot-fw-utils for our u-boot version

This commit creates a class and recipie based on the upstream 2015
branch of u-boot and patches it with our fw_env.config.

Having these tools for the initfs will allow us to modify the u-boot
enviornment to do things like boot from network for update and set the
bmc mac addresses in the environment for u-boot and use by the kernel.

This commit is based on the upstream fw-utils commit.  However, the
initial commit was not creating target binaries.  After commenting
out the cross class support for creating host binaries to prepare
an environment, a study of the u-boot Makefile showed that HOSTCC
etc needed to be set.  It is anticipated something to the commented
lines will be necessary for merging upstream but this addresses our
immediate use case.
