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.
