Subject: [PATCH v2 3/4] arm64: dts: qcom: sdm845: Add the RPMh stats node

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 the node but with a SDM845 dedicated compatible to make
the driver aware of the different stats config.

Signed-off-by: Abel Vesa <abel.vesa@...aro.org>

Changed qcom,rpmh-stats-sdm845 to qcom,sdm845-rpmh-stats, as suggested
by Krzysztof.
