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).
