libata: fix ata_acpi_gtm_xfermask()
ata_acpi_gtm_xfermask() as separated out from pacpi_discover_modes()
has various bugs. Fix them.
* The wrong comparison operator is used when finding for matching
cycle resulting totally bogus result.
* With the comparion operator fixed, boundary condtion handling is
clumsy.
* Setting of any DMA mask bit set all bits in PIO mask.
* MWDMA and UDMA blocks are swapped.
