Subject: [PATCH RFT 00/20] SMD RPMCC sleep preparations

This series brings support for a couple of things necessary for the full
system idle on SMD RPM SoCs, namely unused clk shutdown and keepalive
votes (permanent active votes that are required on certain clocks for the
platform to function).

Tested on MSM8996 and SM6375, does not seem to introduce any additional
regressions.

Keepalive clocks for other platforms were gathered by digging in old
downstream kernels, please give them a test.
