[DistroKit] [PATCH 2/2] v8a: barebox: env: fix boot for i.MX8M EVKs

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Rockchip RK35* and i.MX8M* share the same barebox environment, but RAUC
and bootchooser were only configured for the Rockchip boards, rendering
the i.MX boards unbootable. Fix this by adding bootchooser as boot
target only for the radxa,rock3a.

While at it, we switch to using the new of_compatible command. This is
likey more stable than the Model string and allows easy extension in
future by additional compatibles.
