src/flash/nor: usage/help/doc updates 

Make "usage" messages use the same EBNF as the User's Guide;
no angle brackets.  Improve and correct various helptexts.

Don't use "&function"; a function's name is its address.
Remove a couple instances of pointless whitespace; shrink a
few overlong lines; fix some bad indents.

Add TODO list entry re full support for NAND/NOR bank names.

- NOR flash_write_unlock() does that between sectors
- there may be other cases too
- Make sure all commands accept either a bank name or a bank number,
and be sure both identifiers show up in "flash banks" and "nand list".
Right now the user-friendly names are pretty much hidden...
@subsection thelistflashcfi CFI
- finish implementing bus width/chip width handling (suggested by NC)
