Added the 'fdtcmd' environment variable as a way to provide 'fdt' commands
that the user can supply to manipulate the device tree after
ft_board_setup() and before the tree is handled to the kernel.
The idea is that users may want to add or manipulate nodes w/changing the
u-boot binary.  The current point in the code we do this we have yet to
determine the final size and have yet to do the final fixup of the initrd
information.
If its desirable for the 'fdtcmd' support to have the proper initrd
information a bit of code reorder will be in order.
The current state of the bootm implementation is bad enough, but
adding such a callback opens just another few cans of worms. Sorry,
but I do not want to see that in mainline.

The project was large enough and management communication poor enough
to prompt many members of the team to see themselves  as  contestants
making  brownie  points,  rather  than as builders making programming
products. Each suboptimized  his  piece  to  meet  his  targets;  few
stopped to think about the total effect on the customer.
