  To: Praneeth Bajjuri, Denys Dmytriyenko, Nishant Menon; +Cc: meta-ti

Added KERNEL_DTB_OVERLAY_SUPPORT to individual MACHINE conf to
compile dtbs with symbols. This fixes the issue where the dtbs
are build without symbols causing issue with overlays.

Changes from last version:
1) Added human readable flag KERNEL_DTB_OVERLAY_SUPPORT to control
DTC_FLAGS.
2) The KERNEL_DTB_OVERLAY_SUPPORT is also derived from build-root
usage.

Might be worthwhile to add that enabling overlay support increases the
size of the dtb, hence it is done at a platform level rather than
globally to allow custom boards derived from meta-ti to not pay the
penalty of extra dtb size, yet have the flexibility to enable on need
basis.

Please don't add change log of patch version in commit message. That is
not an information that is useful in git history.

just for the record for other bb files:
linux-ti-staging-rt_5.10.bb linux-ti-staging-systest_5.10.bb 

I think this opens up other possibilities in the future to move common
operations into ti-kernel.inc and probably drop duplications
