numa/cdm: Introduce a hbm_per_part variable

ascend inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4D63I


CVE: NA

-------------------------------------------------

Not all cdm nodes are hbm and we don't need to operate on the other
nodes. So we should specify the hbm count per partion.

Here we assume that all the hbm nodes appear at first of all the cdm
nodes in one partion. Otherwise the management structure of the hbm
nodes could not be moved, which is not worse than closing this feature.
