iq-x5121-evk: add x1 el2 DTBO building and FIT DTB mapping

[Xinzheng Long (xinlon-z)]

KVM support on IQ-X5121 Evaluation Kit requires applying the el2 DTBO at boot. Add FIT_DTB_COMPATIBLE entries to allow UEFI to correctly match and apply the x1-el2.dtbo(shared the same one with IQ-X7181 #2234 ) overlay when booting with KVM.
