powerpc/pmac/smp: Fix CPU hotplug crashes on some machines
On some machines that use i2c to synchronize the timebases (such as PowerMac7,2/7,3 G5 machines), hotplug CPU would crash when putting back a new CPU online due to the underlying i2c bus being closed. This uses the newly added bringup_done() callback to move the close along with other housekeeping calls, and adds a CPU notifier to re-open the i2c bus around subsequent hotplug operations Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
