Subject: [PATCH] sparc: delete "if !ULTRA_HAS_POPULATION_COUNT"

Commit 2d78d4beb64eb07d50665432867971c481192ebf ("[PATCH] bitops:
sparc64: use generic bitops") made the default of GENERIC_HWEIGHT depend
on !ULTRA_HAS_POPULATION_COUNT. But since there's no Kconfig symbol with
that name, this always evaluates to true. Delete this dependency.

0) Tested with "make ARCH=sparc menuconfig" (before and after this
patch).

1) There apparently is an (obscure) preprocessor macro
ULTRA_HAS_POPULATION_COUNT. But the check for it got removed in commit
ef7c4d4675d2a9206f913f26ca1a5cd41bff9d41 ("sparc: Use popc if possible
for hweight routines.").
