Added KERNEL_DTB_OVERLAY_SUPPORT to common ti-soc include. This fixes the issue
where the dtbs are build without symbols causing issue with overlays.
Please note this increases the size of the dtb for all platform
derived from ti-soc. So for custom boards disable it from local.conf to
reduce size.

Changes:
Moved the KERNEL_DTB_OVERLAY_SUPPORT to common ti-soc.inc
This makes it more maintainable and with weak assignement can be
override from local.conf
