ABL uses the __symbols__ section to process the DTB before passing it

Fix your ABL.
Hi Konrad,
Apps boot-loader need __symbols__ for dynamic overlay operation.
Qualcomm firmware passes an overlay file to apps boot-loader to overlay
some of the nodes based on firmware configuration. Without __symbols__
apps boot-loader is not able to overlay.
Qualcomm hypervisor/gunyah would like to overlay arch timer node with
always-on property, So adding __symbols__ helps boot-loader to overlay.
I think, commit text is misleading here and I will request Eric to fix
the commit text.
-Thanks, Prasad
Konrad
