Cache the micro-TLB number in archdata allocated in the .add_device
handler instead of looking it up when the deviced is attached and
detached. This simplifies the .attach_dev and .detach_dev operations and
prepares for DT support.

The driver only supports the 3-level long descriptor format that has no
PUD and always has a PMD.

The IOMMU core will only call us with page sizes advertized as supported
by the driver. We can thus simplify the code by removing loops over PGD
and PMD entries.

Pulled, thanks Laurent,
Thank you. Now, what about the iommu: Add driver for Renesas VMSA-compatible

Hello,
Hi Laurent,

Fixed the commit message. Please find the new patch below:
Thank you. Your mail has wrapped lines and converted tabs to whitespaces.
Could you please fix

or is there a reason to keep loops over PGD and PMD entries ? Removing them
makes the implementation of 68kB and 2MB pages easier.

The contiguous hint bit signals to the IOMMU that a range of 16 PTEs
refer to physically contiguous memory. It improves performances by
dividing the number of TLB lookups by 16, effectively implementing 64kB
page sizes.
