[patch v2] PS3: Fix memory hotplug

[Geoff Levand]

A change was made to walk_memory_resource() in commit
4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a
check of find_lmb().  Add the coresponding lmb_add()
call to ps3_mm_add_memory() so that that check will
succeed.

This fixes the condition where the PS3 boots up with
only the 128 MiB of boot memory.
