sata_inic162x: misc clean ups
* use larger indents for structure member definitions
* kill unused variable @addr in inic_scr_write()
* kill unnecessary flushes in inic_freeze/thaw()
* kill buggy explicit kfree() on devres managed port private data
This is in preparation of further inic162x updates.
