[PATCH 2/2] clk: qcom: smd-rpm: add MSM8920 support

From: "Catherine Frederick (coolguy)" <[email protected]>

MSM8920 is essentially MSM8917 with MSM8953's modem stack, which adds an
IPA (IP Accelerator) block. Add an msm8920 RPM clock table mirroring
msm8917's plus the IPA and IPA_A clocks, and register the
"qcom,rpmcc-msm8920" compatible.

Split out from the combined MSM8920 change so the shared clk-smd-rpm
driver can be reviewed and land via linux-arm-msm independently of the
device tree, as requested in review.
