[libata] pata_amd: program FIFO
With 32bit PIO we can use the posted write buffers, but only for 32bit I/O
cycles. This means we must disable the FIFO for ATAPI where a final 16bit
cycle may occur.
Rework the FIFO logic so that we disable the FIFO then selectively
re-enable it when we set the timings on AMD devices. Also fix a case
where we scribbled on PCI config 0x41 of Nvidia chips when we shouldn't.
