grub2: add support for devicetree

Browse Source 
Similar as available for u-boot (ce2995e1dc1557c4d97ef5af807eacf3ef4a22d8)
and syslinux (c5112c25e4519835c4cd53f4350c1b2f2a477746), enable parsing
and writing devicetree filename into grub.cfg.

This is required by arm64-based devices running edk2 instead of u-boot
as the main bootloader (e.g. 96boards HiKey and HiKey960).
