[PULL,v2,05/23] pc-dimm: add pc_dimm_build_list()

From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

Like pc_dimm_build_list_sorted but not sorted - for cases where sorting
is not necessary. Add stubbed version too - for targets without
CONFIG_MEM_HOTPLUG.

here stubs are deleted. it will break compilation for targets without 
memory hotplug, it was discussed on list. stubs from my patch are 
necessary.
