[PATCH 22/28] 53c700: move bus reset to host reset

Hannes Reinecke
2017-06-28T08:31:13Z

bus reset always returns SUCCESS, meaning host reset was never
tested. At the same time the only difference to the HBA is a
missing call to NCR_700_chip_reset().
So add the missing call to bus reset, drop host reset, and move
bus reset to host reset.
