stm32mp1: dynamically detect op-tee presence
Activate OP-TEE driver for trusted and optee defconfig. This driver allows detection of TEE presence for boot from flash; CONFIG_STM32MP1_OPTEE is also removed. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
