sata_inic162x: misc clean ups

Browse Source 
* 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.
