From: David Engraf <david.engraf@sysgo.com>

Using the whole 128 MiB flash in non-secure mode is not working because
virt_flash_fdt() expects the same address for secure_sysmem and sysmem.
This is not correctly handled by caller because it forwards NULL for
secure_sysmem in non-secure flash mode.

Fixed by using sysmem when secure_sysmem is NULL.
