iommu/omap: add support for late attachment of iommu devices

Browse source

Current implementation of OMAP IOMMU enforces strict ordering of device
probe, initiated by iommu and followed by remoteproc later. This doesn't
work too well with the new setup done with ti-sysc changes which may
have the devices probed at pretty much any order. To overcome this limitation,
if iommu has not been probed yet when a consumer tries to attach to it,
add the device to orphan device list which will be parsed during iommu
probe to see if any orphan devices should be attached.
