x86/sched: Restore the SD_ASYM_PACKING flag in the DIE domain

x86/sched: Restore the SD_ASYM_PACKING flag in the DIE domain

Commit 8f2d6c41e5a6 ("x86/sched: Rewrite topology setup") dropped the
SD_ASYM_PACKING flag in the DIE domain added in commit 044f0e27dec6
("x86/sched: Add the SD_ASYM_PACKING flag to the die domain of hybrid
processors"). Restore it on hybrid processors.

The die-level domain does not depend on any build configuration and now
x86_sched_itmt_flags() is always needed. Remove the build dependency on
CONFIG_SCHED_[SMT|CLUSTER|MC].
