Add description of new CPU hotplug interface. To switch from from legacy mode into new mode use fact that write accesses into CPU present bitmap were never used before and were ignored by QEMU. So use it to as a way to switch from legacy mode. That way pc/q35 machine starts in legacy mode and QEMU generated ACPI tables will switch to new CPU hotplug interface during runtime. In case QEMU is started with legacy BIOS (that doesn't support QEMU generated ACPI tables), legacy CPU hotplug will remain active and could be used by BIOS built in ACPI tables for CPU hotplug.
