Hisilicon: Embed device trees to firmware
Firmware provided device tree is preferred for Generic Linux
distributions (Debian, Ubuntu, Fedora, Suse). The main motivation
is to have an identical rootfs than can work on many different devices.
The alternative is to Bundle Kernel + dtb, or have board-specific grub
files. Both would mean board-specific rootfs.
This change uses DtPlatformDtbLoaderLib, either backported lib in edk2
is required or rebasing edk2 to newer upstream version.
