libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO

Browse source 
Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq()
so the latter can be also used for host controllers supporting
32-bit PIO operations.

It is a completely safe thing to do because if 32-bit PIO is
not supported or enabled ata_sff_data_xfer32() will fallback
to a standard method.
