Clean-up for omap PRCM (Power Reset Clock Management) and interconnects
from Tero Kristo <t-kristo@ti.com>.

This sets gets us into a better position for further clean-up:

- Gets PRCM code closer to being device drivers

- Allows to move the remainig clock code to drivers/clk for v4.2

- Starts enforcing interconnect hierarchy in the SoC specific .dts
  files to enforce device drivers are only accesing registers in
  the related hardware module

This patchset has seen quite a few revisions but did not come into
mergeable shape until recently. As other patchsets for clock specific
device drivers depend on this, it would be good to get this merged
although it's a bit late for the v4.1 merge window.

Note that as the device entries in the .dts files are moved around,
this is based on earlier non-urgent fixes to avoid a non-trivial
merge conflict.
Merge branch '4.0-rc1-prcm-cleanup-v6' of https://github.com/t-kristo/linux-pm into omap-for-v4.1/prcm-cleanup
