Subject: [PATCH 1/3] scsi: hisi_sas: Reduce some indirection in v3 hw driver

Sometimes local functions are called indirectly from the hw driver, which
only makes the code harder to follow. Remove these.

Method .hw_init is only called from platform driver probe, which is not
relevant, so don't set this either.
