[PATCH v1.1] drivers: parisc: Update sba_iommu driver with proper printks

From: Carlos Bilbao
Date: Fri Jul 09 2021 - 13:19:28 EST

The code from the old SBA IOMMU manager is outdated when it comes to printks.
Fix applying proper indentation and using pr_debug() instead of printk on
debugging blocks. Also add a KERN_<LEVEL> where it is missing.
