[edk2-platforms][PATCH V1 03/20] StandaloneMmPkg: Include libfdt in the StMM

["Nishant Sharma" <nishant.sharma@arm.com>]

From: Achin Gupta <achin.gupta@arm.com>

The StMM SP will extract boot information from its manifest instead of a C
data structure populated by the SPM. The manifest will be passed by the
SPM. This patch includes support for libfdt to prepare for parsing the
manifest in future patches.
