[PATCH 2/2] optee: add property no-map to secure reserved memory

[Patrice Chotard]

From: Etienne Carriere <etienne.carri...@st.com>

OP-TEE reserved memory node must set property "no-map" to prevent
Linux kernel from mapping secure memory unless what non-secure world
speculative accesses of the CPU can violate the memory firmware
configuration.

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