Introduce handling of driver options. Options are set based on DT
information when probing an SMMU device. The first option introduced
is arm,smmu-isolate-devices. (It will be used in the bus notifier
block.)

At the moment just handle BUS_NOTIFY_BIND_DRIVER to conditionally
isolate all master devices for an SMMU.
Depending on DT information each device is put into its own protection
domain (if possible). For configuration with one or just a few
masters per SMMU that is easy to achieve.
In case of
In such a case we have to use secure aliases of some non-secure
registers.
This handling is switched on by DT property
calxeda,smmu-secure-config-access for an SMMU node.

arm-smmu driver uses of_parse_phandle_with_args when parsing DT
information to determine stream IDs for a master device.
Thus the number of stream IDs per master device is bound by
MAX_PHANDLE_ARGS.
To support Calxeda ECX-2000 hardware arm-smmu driver requires a
slightly higher value for

This patch adds descriptions fore new properties of device tree
binding for the ARM SMMU architecture. These properties control
arm-smmu driver options.

Try to determine a mask that can be used for all StreamIDs of a master
device. This allows to use just one SMR group instead of
number-of-streamids SMR groups for a master device.
Changelog:
* dropped #define DEBUG
* removed BUG_ON(!is_power_of_2(nr)) from determine_smr_mask
by passing an
Instead of using just one bitmap to keep track of IO virtual addresses
(handed out for IOMMU use) introduce a list of iova_ranges (each
having its own bitmap). This allows us to extend existing mappings
when running out of iova space for a mapping.
If there is not enough space in the mapping to
