ata: pata_platform: fix owner module reference mismatch for scsi host
The owner module reference of the pata_of_platform's scsi_host is
initialized to pata_platform's one, because pata_of_platform driver
use a scsi_host_template defined in pata_platform. So this drivers
can be unloaded even if the scsi device is being accessed.
This fixes it by propagating the scsi_host_template to pata_of_platform
driver. The scsi_host_template is passed through a new
argument of __pata_platform_probe().
