u-boot: Fix booting raspberrypi CM3 module

With stock u-boot v2020.01 which we use from poky CM3 module won't boot.
We need to apply this patch in order to have platform again working.

Add it only for cm3 to not break anything else.

+Subject: [PATCH] dm: core: Move ofdata_to_platdata() call earlier
+
+This method is supposed to extract platform data from the device tree. It
+should be done before the device itself is probed. Move it earlier in the
+device_probe() function.
+
+Upstream-Status: Backport
