The generic IOMMU binding says that the meaning of an 'IOMMU specifier'
is defined by the binding of a specific SMMU. The ARM SMMU binding
never explicitly uses the term 'specifier' at all. Update implicit
references to use the explicit term.
In the iommu-map binding change references to iommu-specifier to
"IOMMU specifier" so we are 100% consistent everywhere with terminology
and capitalization.

The existing IOMMU bindings are able to specify the relationship between
masters and IOMMUs, but they are insufficient for describing the general
case of hotpluggable busses such as PCI where the set of masters is not
known until runtime, and the relationship between masters and IOMMUs is
a property of the integration of the system.
This patch adds a generic binding for mapping PCI devices to IOMMUs,
using a new iommu-map property (specific to PCI*) which may be used to
map devices (identified by their Requester ID) to sideband data for the
IOMMU which they master through.
