arm, arm64: Fix selection of CONFIG_SCHED_THERMAL_PRESSURE
Qian reported that the current setup forgoes the Kconfig dependencies and
results in warnings such as:
WARNING: unmet direct dependencies detected for SCHED_THERMAL_PRESSURE
Depends on [n]: SMP [=y] && CPU_FREQ_THERMAL [=n]
Selected by [y]:
- ARM64 [=y]
Revert commit
e17ae7fea871 ("arm, arm64: Select CONFIG_SCHED_THERMAL_PRESSURE")
and re-implement it by making the option default to 'y' for arm64 and arm,
which respects Kconfig dependencies (i.e. will remain 'n' if
CPU_FREQ_THERMAL=n).
