Subject: [PATCH] kconfig: remove SYMBOL_NO_WRITE flag
This flag is set to symbols that are not intended to be written
to the .config file.
Since commit b75b0a819af9 ("kconfig: change defconfig_list option to
environment variable"), SYMBOL_NO_WRITE is only set to choices.
Therefore, (sym->flags & SYMBOL_NO_WRITE) is equivalent to
sym_is_choice(sym). This flags is no longer necessary.
