This patch does the required changes to enable CSS platforms to build and use the SDS framework. Since SDS is always coupled with SCMI protocol, the preexisting SCMI build flag is now renamed to `CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on CSS platforms. Also some of the workarounds applied for SCMI are now removed with SDS in place. Change-Id: I94e8b93f05e3fe95e475c5501c25bec052588a9c Signed-off-by: Soby Mathew <soby.mathew@arm.com>
