The ipu device is missing from the omap_ipupm_data. This
results in a null device pointer being used when applying
constraints. This change provides an api which can be used
to return a device when queried by name. This is to support
initializing omap_ipupm_data with a device.

In case omap_hwmod_lookup returns NULL, don't proceed further for this
instance and continue with next device.

The DVFS framework for DSP is dependent on hwmod registeration completed for
DSP in iommu driver. This patch moves the iommu initialization to post-core
init to ensure the registeration is completed prior to DVFS stuff.
Without this fix, the following warning was observed during boot-up.

omap:iodmm-dmm code moved to new file and fixes
The patch handles the following
1. Moved the code out of iovmm to new file.
2. Removed the config option related to IOVMM in makefile
3. Moved the DMM pool creation part to iodmm.c
4. Removed the hacks that were made to handle Tiler buffers.
5. Only buffers that are mapped would be permittted for flushing.
6. Removed the ioctl to program PTE entries directly from userspace.
Regular DMM should be used to program the PTE entries. This requires
userspace change
7. Removed unused functions.
8. Provided the support to map Anonymous buffers.
9. Provided the support to map Physical address if passed.
10. Replaced the local spinlock with global mutex lock for critical
critical sections.

omap:iodmm-allow unconditional cache flush

It seems dsp-link will do this, and tidspbridge too at some point, but
right now it's not possible to select CONFIG_MPU_BRIDGE_IOMMU.
