doc: Switch from printenv to env print
The "env" command is the recommended environment management command,
its "print" subcommand is the equivalent replacement for legacy "printenv"
command. Update the documentation to use the contemporary "env print"
command instead of legacy "printenv" command.
Note that the "printenv" command is unlikely to be removed from U-Boot
in the near future due to it being integral part of the command line
ABI.
Implemented using:
$ sed -i 's@\<printenv\>@env print@g' $(git grep -li '\<printenv\>' doc/) README
