it reduces number of args passed in handlers by 1 and
a number of used proxy wrappers saving ~20LOC.
Also it allows to make cpu/mem hotplug code more
universal as it would allow ARM to reuse it without
rewrite by providing its own send_event callback
to trigger events usiong GPIO instead of GPE
as fixed hadrware ACPI model doen't have GPE at all.

since IO block used by CPU hotplug is fixed size and
initialized it the same file as build_legacy_cpu_hotplug_aml()
just use ACPI_GPE_PROC_LEN directly instead of passing
it around in several files.
