Add support for arm Foundation ARMv8 FVP simulator

Add recipes and configuration files to add Yocto support for Foundation armv8 simulator from arm. The following components are supported: - trusted-firmware-a - linux kernel (with specific kernel configuration) - xen (with meta-virtualization layer) - unpacking and starting the generated image directly in Foundation simulator (package must be download from www.arm.com website and put in the directory downloads/licensed/silver.arm.com). After building, the following command can be used to start a generated image in foundation: ./tmp/deploy/tools/start-foundation-armv8.sh Change-Id: Iade343c38f0799ee8523434d555cb3ca42068a86 Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>

+# Defines the disk.img image type

+#
+# Add an image type 'disk.img' which creates a disk image
+# with up to 4 partitions

+#
+# * DISK_IMG_PARTITION1_SIZE is the partition size in MB (1024 is 1 GB)
+#
+# * DISK_IMG_PARTITION1_FSTYPE is the file system to format the partition with.
+#   We support only ext files systems (ext2, ext3 and ext4)
+#   If this is empty, the partition will not be formated.
+#
+# * DISK_IMG_PARTITION1_CONTENT is the content to put in the filesystem.
+#   Only 'rootfs' is supported and will create a partition with the Yocto
+#   root filesystem.
