Simon Glass bb74837c9a binman: Support an entry that holds text
It is useful to able to write an identifying string to the image within an
entry. Add a 'text' entry type to handle this. The actual text is
typically passed to binman on the command line. The text is not itself
nul-terminated but this can be achieved if required by setting the size of
the entry to something larger than the text.

"""An entry which contains text
The text can be provided either in the node itself or by a command-line
argument.
Example node:
text {
size = <50>;
text-label = "message";
};
You can then use:
binman -amessage="this is my message"
and binman will insert that string into the entry.
It is also possible to put the string directly in the node:
text {
size = <8>;
text-label = "message";
message = "a message directly in the node"
};
The text is not itself nul-terminated. This can be achieved, if required,
by setting the size of the entry to something larger than the text.
