Add camx el2 DT overlay for lemans/sa8775p platforms.

[quic-vikramsa]

The overlay updates the ICP firmware node with Secure SMMU SID and disables secure QoS updates for CPAS in EL2/KVM configurations. Wire up the new overlay-built DTBs in the qcom DT Makefile so the corresponding *-camx-el2.dtb targets are generated.

What is camx-el2? Why is it required.

camx-el2 DT overlay is used to enable camera firmware loading when the kernel runs at EL2 under KVM.

In what condition this overlay is going to be applied.

It is applied only when the system boots with KVM enabled, instead of regular camx overlay.

Please discuss internally first.

Sure

Change looks good to me.
