[PATCH 1/2] drm/amd/pm: correct gpu metrics related data structures V3

To make sure they are naturally aligned. Also updating the
data type for link_speed/width for future PCIE5 support.
V2: define new structures with minor version bumped
V3: update data type of energy_accumulator as 64bit and
drop unnecessary padding members
