iommu/omap: eliminate the public omap_find_iommu_device() method
Eliminate the public omap_find_iommu_device() method, and don't
expect clients to provide the omap_iommu handle anymore.
Instead, OMAP's iommu driver now utilizes dev_archdata's private iommu
extension to be able to access the required iommu information.
This way OMAP IOMMU users are now able to use the generic IOMMU API without
having to call any omap-specific binding method.
Update omap3isp appropriately.

ARM: OMAP: iommu: declare a private iommu binding struct
Declare an omap iommu private struct, which binds an iommu user
to its iommu device. This struct should be placed at the iommu user's
dev_archdata so generic IOMMU API can be used without having to
utilize omap-specific plumbing anymore.
While at it, provide an accessor method to ease the retrieval of the
omap_iommu handle from a user device.

iommu/omap: Migrate to the generic fault report mechanism
Start using the generic fault report mechanism, as provided by
the IOMMU core, and remove its now-redundant omap_iommu_set_isr API.
Currently we're only interested in letting upper layers know about the
fault, so in case the faulting device is a remote processor, they could
restart it.
Dynamic PTE/TLB loading is not supported.

omap: iommu: omapify 'struct iommu' and exposed API
Prepend 'omap_' to OMAP's 'struct iommu' and exposed API, to prevent
namespace pollution and generally to improve readability of the code
that still uses the driver directly.
Update the users as needed as well.

omap: iommu: remove unused exported API
Remove unused public APIs from OMAP's iommu driver.
IOMMU functionality should be exposed only via the generic IOMMU API;
this way drivers stay generic, and different IOMMU drivers
don't need to duplicate similar functionalities.
The rest of the API still exposed by OMAP's iommu will be evaluated
and eventually either added to the generic IOMMU API (if relevant),
or completely removed.
The intention is that OMAP's iommu driver will eventually not expose
any public API.

omap: iommu: migrate to the generic IOMMU API
Migrate OMAP's iommu driver to the generic IOMMU API, so users can stay
generic, and any generic IOMMU functionality can be developed once
in the generic framework.
Migrate omap's iovmm (virtual memory manager) to the generic IOMMU API,
and adapt omap3isp as needed, so the latter won't break.
The plan is to eventually remove iovmm completely by replacing it
with the (upcoming) IOMMU-based DMA-API.
Tested on OMAP3 (with omap3isp) and OMAP4 (with rpmsg/remoteproc).

omap iommu: add functionality to get TLB miss interrupt
In order to enable TLB miss interrupt, the TWL should be
disabled. This patch provides the functionality to get the
MMU fault interrupt for a TLB miss in the cases where the
users are working with the locked TLB entries and with TWL
disabled.
New interface is added to select twl and to enable TLB miss
interrupt.
