 kconfig: forbid multiple entries with the same symbol in a choice 
Commit 6a859f1a19 ("powerpc: unify two CONFIG_POWERPC64_CPU entries
in the same choice block") removed the only occurrence of this tricky
use case.

Disallow this pattern in choice_check_sanity() and revert commit
4d46b5b623 ("kconfig: fix infinite loop in sym_calc_choice()").
