Revert "ARM64: Dynamically allocate cpumasks and increase supported C…

…PUs to 512" This reverts commit 0499a78. Enabling CPUMASK_OFFSTACK on arm64 triggers a warning in the dev_pm_opp_set_config() function followed by a failure to set the regulators and cpufreq-dt probing error. There is no apparent reason why this happens, so revert this commit until further investigation.
