kconfig: remove SYMBOL_CHOICE flag

Browse Source 
All symbols except choices have a name.

Previously, choices were allowed to have a name, but commit c83f020973
("kconfig: remove named choice support") eliminated that possibility.

Now, it is easy to distinguish choices from normal symbols; if the name
is NULL, it is a choice.
