Subject: [PATCH v4 02/41] ata: add HAS_IOPORT dependencies
In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.
Co-developed-by: Arnd Bergmann <arnd@...nel.org>

Note: The HAS_IOPORT Kconfig option was added in v6.4-rc1 so
per-subsystem patches may be applied independently
