x86: apl: Use devicetree for FSP-S configuration

A the moment the FSP-S configuration is a mix of hard coded values and devicetree properties. This patch makes FSP-S full configurable from devicetree by adding binding properties for all FSP-S parameters.

+* Intel FSP-S configuration
+
+Several Intel platforms require the execution of the Intel FSP (Firmware
+Support Package) for initialization. The FSP consists of multiple parts, one
+of which is the FSP-S (Silicon initialization phase).
+
+This binding applies to the FSP-S for the Intel Apollo Lake SoC.
+
+The FSP-S is available on Github [1].
+For detailed information on the FSP-S parameters see the documentation in
+FSP/ApolloLakeFspBinPkg/Docs [2].
+
+The properties of this binding are all optional. If no properties are set the
+values of the FSP-S are used.
