[Qemu-devel] [PATCH] hw/arm/virt: add DT property /secure-chosen/sdtout-path being secure UART |

Bindings for /secure-chosen and /secure-chosen/stdout-path have been
proposed 1.5 years ago [1] and implemented in OP-TEE at the same time [2].
This patch creates the property when the machine is secure.
