[PATCH] env: Allow string CONFIG options in the text environment

Hi Simon,
I got no time to try it yet but I have a general comment.

wouldn't it be cleaner to always convert a Kconfig option which is defined as a string
to a string without the double quotes? If someone needs them he could explicitly
add them with

bootcmd=run "CONFIG_BOARD_CMD"

Because  in my case I have some options I use them to build together the
kernel command line I pass to the kernel.  Ok I could store them before in an
own variable and them use them with ${variable} in the command line. But
I think it would be cleaner to always convert a string defined in Kconfig in a
string without the quotes. What do you think?

just out of curiosity as we are also using similar things in our environment, the
double quotes in this case are not needed or?
