ARM: shmobile: Remove legacy machine_desc.map_io() callbacks

Hi Simon, Magnus,

This patch series removes the legacy machine_desc.map_io() callback for SoCs that no longer rely on it, but use ioremap() instead.

The patch for emev2 depends on "ARM: shmobile: Consolidate SCU mapping code" ("FIXME" commit ID reference to be updated).

Thanks!

Commit 37201ba5c99d0be8 ("ARM: shmobile: r8a7740: Migrate to generic l2c OF initialization") removed the last user of the legacy "IOMEM()" macro on r8a7740-based systems. Hence there's no longer a need to set up a transparent mapping of system I/O registers. Remove the mapping and the legacy machine_desc.map_io() callback.

Commit FIXME ("ARM: shmobile: Consolidate SCU mapping code") removed the last user of the static mapping on emev2-based systems. Remove the mapping and the legacy machine_desc.map_io() callback.

Thanks, I have queued these up.

Hi Simon,

Thanks, but unfortunately it's not in renesas-devel-20160205-v4.5-rc2?

Sorry about that, I'll try to actually queue it up this time.
