ata: sata_fsl: fix scsi host initialization
When compiling with W=1, the sata_fsl driver compilation throws the
warning:
drivers/ata/sata_fsl.c:1385:22: error: initialized field overwritten
[-Werror=override-init]
1385 | .can_queue = SATA_FSL_QUEUE_DEPTH,
This is due to the driver scsi host template initialization overwriting
the can_queue field that is already set using the ATA_NCQ_SHT()
initializer macro, resulting in the same field being initialized twice
in the host template declaration.
To remove this warning, introduce the ATA_SUBBASE_SHT_QD() and
ATA_NCQ_SHT_QD() initialization macros to allow specifying a queue depth
different from the default ATA_DEF_QUEUE using an additional argument to
the macro.
