arm64: smp: Defer update of secondary CPU capabilities
check_local_cpu_capabilities() runs relatively early during the boot of
each secondary CPU and, despite its name, calls update_cpu_capabilities()
to manipulate the global 'system_cpucaps' based on the features detected
by the incoming CPU.
In preparation for parallel bringup of secondary CPUs, move the call
to update_cpu_capabilities() into update_cpu_features(), allowing
check_local_cpu_capabilities() to run concurrently in future, as it now
only performs local verification of the incoming CPU.
