[PATCH v6 0/2] m68k: pata_cswarp: Add Amiga cslab ata support

[Paolo Pisati <p.pisati@gmail.com>]

Here is a driver (and the subsequent defconfig change) for the pata/CF socket in
the CS-Lab Warp series of Amiga boards.

This is a respin of v5 addressing Geert's and sashiko-bot's review.

Tested on real Warp hardware.

v5: https://lore.kernel.org/linux-ide/20260824153339.512487-1-p.pisati@gmail.com/

Changes in v6:
 - fix 7.3 FTBFS (include <linux/device-id/zorro.h>, and use named initializers in
   the zorro_device_id table)
 - use devm_ioremap()
 - print the register window with %pR in ata_port_desc()

Changes in v5:
 - return the number of bytes actually consumed on the bus
 - fix the trailing byte in pata_cswarp_data_xfer()
 - drop a blank line in Kconfig
 - fix the remaining checkpatch complaints

Changes in v4:
 - refactor pata_cswarp_data_xfer()
 - ioremap WARP_OFFSET_ATA region

Changes in v3:
 - suppress a comment
 - properly return ata_host_activate() error code

Change in v2:
 - fix style, remove duplicate swap macro, driver version, etc
 - rework the zorro attach mechanism
 - remove the unnecessary zorro ids refactor
