Move FSP-M configuration to the device-tree like it's already done for
other SoCs (Baytrail).
Signed-off-by: Bernhard Messerklinger <bernhard.messerklin...@br-automation.com>
---
With this patch I moved the FSP-M configuration to the device-tree based
on the Baytrail boards.
Changes in v3:
Added doc binding file
Added fspm prefix to some variables
Changes in v2:
Added commit notes

+* Intel FSP-M configuration
+
+This configuration applies to the FSP-M for the Intel Apollo Lake SoC.
+The FSP-M can be found on https://github.com/IntelFsp/FSP.
+For detailed information see FSP/ApolloLakeFspBinPkg/Docs.
+If no configuration parameters are set the default FSP-M configuration is set.
+For example Memory Fast Boot is an enable option in the FSP which is enabled by
+default, so the configuration option is named fspm,disable-mrc-fast-boot.
