[PATCH v5 0/2] m68k: pata_cswarp: Add Amiga cslab ata support

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 v4 addressing Geert's review - apologies for the long delay.

Tested on real Warp hardware.

v4: https://lore.kernel.org/linux-ide/[email protected]/

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
