Changes since v1:
- rebase against official linux tree. v1 was based against a local tree and didn't apply cleanly.
Changes since v2:
- fix typo KERN_ERROR -> KERN_ERR
Changes since v3:
- fix circuit adjust (reserved bits should be 1)
- don't initialize priv in mc44s803_attach()
- use a macro for printk to avoid duplicating the driver name over and over.
