optee: copy FDT OP-TEE related nodes before generic FDT changes

Move call to optee_copy_fdt_nodes() introduced by commit 6ccb05eae01b
before generic changes in kernel FDT so that platform specific changes
are not overridden by the changes made by this function.

Fixes: 6ccb05eae01b ("image: fdt: copy possible optee nodes to a loaded devicetree")
