Revert "ata: ahci: force 32-bit DMA for JMicron JMB582/JMB585"
This reverts commit 105c42566a550e2d05fc14f763216a8765ee5d0e.
The 32-bit quirk was incorrectly applied to JMicron JMicron JMB582/JMB585,
but it turns out that the root cause was actually a problem with BIOS
configuration of PCIe root ports, enabling a features that causes problems
with 64-bit DMA.
This problem has now been fixed in commit 4fde44822512 ("x86/PCI: Disable
enhanced atomics on AMD NBIO 7.7 and 7.11").
Since the real root cause has now been fixed, we can revert this incorrect
quirk.
