Subject: [PATCH] arm: dts: allwinner: enable overlay support for sun8i-h2-plus
 pi boards

Add DTC_FLAGS -@ for all H2+ pi-class devices to enable device-tree
overlay support. This follows the same approach used for H3 pi boards
in commit 0801a3a9f35854c91f1f3ab8e879c3d14912d214 ("arm: dts: Enable
device-tree overlay support for sun8i-h3 pi devices").

The -@ flag populates the __symbols__ node in the DTB which is required
for applying device-tree overlays from the bootloader or firmware.

Boards affected:
- sun8i-h2-plus-bananapi-m2-zero
- sun8i-h2-plus-libretech-all-h3-cc
- sun8i-h2-plus-orangepi-r1
- sun8i-h2-plus-orangepi-zero
