arm: dts: Enable device-tree overlay support for AT91 boards
Add the '-@' DTC option for AT91 boards that have device-tree overlays.
This option populates the '__symbols__' node that contains all the
necessary symbols for supporting device-tree overlays (from bootloader)
on these devices.
This change increases the size of the resulting DTB with ~30%-40%. Below
are the measurements performed v6.4-rc6:
