[MTD] maps/ixp4xx: kill some warnings
- Use map.virt instead of map.map_priv_1 since it has the correct type. - Use readw/writew instead of dereferencing an ioremap'd cookie. - Remove an unused variable. Signed-off-by: David Vrabel <dvrabel@arcom.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
