ata: ahci_platform: fix owner module reference mismatch for scsi host
The owner module reference of the ahci platform's scsi_host is
initialized to libahci_platform's one, because these drivers use a
scsi_host_template defined in libahci_platform. So these drivers can
be unloaded even if the scsi device is being accessed.
This fixes it by pushing the scsi_host_template from libahci_platform
to all leaf drivers. The scsi_host_template is passed through a new
argument of ahci_platform_init_host().
