armv8: LSCH2 early and final mmu needs matching NS attribute
When switching between the early and final mmu tables, the stack will
get corrupted if the Non-Secure attribute is different. For ls1043a,
this issue is currently masked because flush_dcache_all is called
before the switch when CONFIG_SYS_DPAA_FMAN is defined.
