ANDROID: drivers/base/arch_topology: Dynamic sched_domain flag detection

This patch add support for dynamic sched_domain flag detection. Flags
like SD_ASYM_CPUCAPACITY are not guaranteed to be set at the same level
for all systems. Let the arch_topology driver do the detection of where
those flags should be set instead. This patch adds initial support for
setting the SD_ASYM_CPUCAPACITY flag.
