cpu/hotplug: Provide weak fallback for arch_cpuhp_init_parallel_bringup()

Browse source

CONFIG_HOTPLUG_PARALLEL expects the architecture to implement
arch_cpuhp_init_parallel_bringup() to decide whether paralllel hotplug is
possible and to do the necessary architecture specific initialization.

There are architectures which can enable it unconditionally and do not
require architecture specific initialization.

Provide a weak fallback for arch_cpuhp_init_parallel_bringup() so that
such architectures are not forced to implement empty stub functions.
