soc: qcom: stats: Add SDM845 stats config and compatible

SDM845 is a special case compared to the other platforms that use RPMh
stats, since it only has 2 stats (aosd and cxsd), while the others have
a 3rd one (ddr).

So lets add dedicated stats config and compatible for SDM845 to make the
driver aware of this num_records difference.
