[PATCH] drm/amd/pm: correct gpu metrics related data structures V2

[Evan Quan]

To make sure they are naturally aligned.

V2: minimum the possible influence to existing applications which
    were developed based on those data structures. With this change,
    only 32bit OS are affected while 64bit OS not.
