Arthur Husband 105c42566a ata: ahci: force 32-bit DMA for JMicron JMB582/JMB585 
The JMicron JMB585 (and JMB582) SATA controllers advertise 64-bit DMA
support via the S64A bit in the AHCI CAP register, but their 64-bit DMA
implementation is defective. Under sustained I/O, DMA transfers targeting
addresses above 4GB silently corrupt data -- writes land at incorrect
memory addresses with no errors logged.

The failure pattern is similar to the ASMedia ASM1061
(commit 20730e9b27 ("ahci: add 43-bit DMA address quirk for ASMedia
ASM1061 controllers")), which also falsely advertised full 64-bit DMA
support. However, the JMB585 requires a stricter 32-bit DMA mask rather
than 43-bit, as corruption occurs with any address above 4GB.

On the Minisforum N5 Pro specifically, the combination of the JMB585's
broken 64-bit DMA with the AMD Family 1Ah (Strix Point) IOMMU causes
silent data corruption that is only detectable via checksumming
filesystems (BTRFS/ZFS scrub). The corruption occurs when 32-bit IOVA
space is exhausted and the kernel transparently switches to 64-bit DMA
addresses.

Add device-specific PCI ID entries for the JMB582 (0x0582) and JMB585
(0x0585) before the generic JMicron class match, using a new board type
that combines AHCI_HFLAG_IGN_IRQ_IF_ERR (preserving existing behavior)
with AHCI_HFLAG_32BIT_ONLY to force 32-bit DMA masks.
