This change introduces configurations CFG_EMDED_DTB and
CFG_EMBED_DTB_SOURCE_FILE. When CFG_EMDED_DTB=y a device
tree blob (DTB) is embedded in a read-only section of the
core based on an in-tree device tree source (DTS) file.
CFG_EMBED_DTS_SOURCE_FILE defines the relative path of
the target device in core/arch/$(ARCH)/dts.
Non empty CFG_EMBED_DTS_SOURCE_FILE content implies CFG_EMBED_DTB=y.
CFG_EMBED_DTB=y mandates CFG_EMBED_DTS_SOURCE_FILE definition.
CFG_EMDED_DTB=y mandates CFG_DT=y.
Since the embedded DTB is read-only, core do not attempt to
modify it adding information such as OP-TEE resources nodes and
properties. Core still get generic information such as system
memory address range and debug console configuration
from the embedded DTB.
Documentation includes a DT section in the OP-TEE design
description.
