drivers: versal_net: Add OCP driverOn Versal NET devices (only) PLM Firmware has a module called XilOCP,providing services related to the Open Compute Project (OCP) securitystandards (PCR handling, Device Management Endorsement, Attestation).This commit adds functions which are more or less equivalent to the XilOCPclient side API offers.Since most Versal and Versal NET drivers more or less re-implement rathersimilar handling of struct versal_ipi_cmd, this commit also adds and herebyproposes a new set of helper functions for commonly used operations onstruct versal_ipi_cmd. With these versal_ipi_cmd_*() functions datawords ("Values") and "IPI buffers" can easily be "pushed" onto a structversal_ipi_cmd.For now, only this OCP driver makes use of these versal_ipi_cmd_*()functions. Thus they have been placed directly in versal_ocp.c instead ofhaving them located in a separate drivers/ file, likedrivers/versal_ipi_cmd.c [1].Link: https://github.com/OP-TEE/optee_os/pull/7726#issuecomment-4237954478 [1]Signed-off-by: Dennis Ries Signed-off-by: Joachim Foerster Reviewed-by: Nathan Menhorn Tested-by: Nathan Menhorn Reviewed-by: Sean McGinn Reviewed-by: Lucas Kiker Reviewed-by: Sindhu Raveendra Reviewed-by: Clemens Nasenberg Reviewed-by: Jorge Ramirez-Ortiz List of files: /optee_os/core/drivers/versal_pmc.c
