soc: rockchip: add header for ddr rate SIP interface Add a header for the SIP interface defined to access the dcf controller handling ddr rate changes on rk3399 (and most likely later socs). This interface is shared between the clock driver as well as the devfreq driver. The SIP interface counterpart was merged from pull-request #684 [0] into the upstream arm-trusted-firmware codebase.

PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A. Trusted Firmware-A (TF-A) for rk3399 implements a SiP call to get the on-die termination (ODT) and auto power down parameters from kernel, this patch adds the functionality to do this. Also, if DDR clock frequency is lower than the on-die termination (ODT) disable frequency this driver should disable the DDR ODT.
