A9 gtimer includes global control field and number of per-cpu fields.
But only per-cpu ones are migrated. This patch adds a subsection for

SC is required for some kernel features like vhost-vDPA. So this patch
implements basic SC feature. The idea is pretty simple, for software
emulated DMA it would be always coherent. In this case we can simple
