Subject: [PATCH v2 0/2] Qualcomm Ramp Controller and MSM8976 config

This series adds the Qualcomm Ramp Controller driver, necessary on
various legacy Qualcomm SoCs to enable CPU DVFS by programming said
controller with the right values, where the bootloader doesn't do
that before booting the kernel.

At least MSM8976 and MSM8956 require this initial programming to be
performed on Linux.

Changes in v2:
 - Fixed yaml issues as per Krzysztof's review
 - Reworded s/linking/link/g in both yaml and Kconfig help
 - Constified reg_sequence pointers
 - Removed spaces before defines
 - Added COMPILE_TEST to Kconfig entry
