I am currently porting Xen on an N1SDP arm board which is also using a 
EDK2/grub setup and I manage to start xen from grub and then start dom0 
providing a DTB.

My grub configuration looks like this:
menuentry 'xen' {
    xen_hypervisor $prefix/xen.efi loglvl=all guest_loglvl=all console=dtuart 
dtuart=serial0 dom0_mem=1G
    xen_module $prefix/Image console=hvc0 efi=noruntime rw root=/dev/sda1 
    devicetree $prefix/n1sdp.dtb

Could you share your grub configuration ?
