The am625 is capable of running at 1.4 GHz when VDD_CORE is increased

increase the VDD_CORE voltage accordingly.
The entire argument in introducing the 1.4Ghz overlay seems to have been
to let users have the choice. What has changed since then?
I talked with the team and we came back with the following:
- Our default PMIC configuration changed for 850000 uV / 1.4 GHz operations
- All available users will receive a PCN on update with instructions
towards 850000 uV / 1.4 GHz operations
These changes make this overlay obsolete.

btw, instead of putting a patch to delete the dtso, you should
probably consider a revert patch instead.
Thank you, I will send a v2 Monday reverting this patch instead. This
will also address the Makefile edits.
Regards,
Garrett
