Revert "ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512" 

This reverts commit 0499a78369.

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.
