[PATCH 2/5] arm: dts: st: Import optee node from u-boot device trees

[Mathieu Dubois-Briand <mathieu.dubois-briand@bootlin.com>]

U-Boot is importing kernel device trees for these platforms, but adding
a firmware node to enable communication with OP-TEE. Importing
changes here will allow to remove these additions in U-Boot.

Also import the corresponding reserved-memory region.
