Due to Errata in ThunderX, HOST_IRQ_STAT should be
cleared before leaving the interrupt handler.
The patch attempts to satisfy the need.

Changes from V2:
- removed newfile
- code is now under CONFIG_ARM64

Changes from V1:
- Rebased on top of libata/for-4.6
- Moved ThunderX intr handler to new file

Signed-off-by: Tirumalesh Chalamarla <tchalamarla@xxxxxxxxxxxxxxxxxx>

Applied to libata/for-4.5-fixes w/ minor adjustments to comments.
