Invalidate a Data cache line.
The cacheline is cleaned and invalidated.
Note: In Cortex-A53, functionality to simply invalid the cachelines is not present. Such operations are a problem for an environment that supports virtualisation. It would allow one OS to invalidate a line belonging to another OS. This could lead to the other OS crashing because of the loss of essential data. Hence, such operations are promoted to clean and invalidate to avoid such corruption.
