Now that we have per-user clocks and the possibility to set constraints
in a clock, set a floor constraint on the EMC clock.

There seemed to be some miscommunication and an old version of the
submitted patches was merged.

This commit updates the driver to v5, which had this changelog:

* Clarify the units of avg_dependency_threshold
* Remove unused references to platform_device
* Enable and disable interrupts on governor events
* Make sure we handle all interrupts for any of the devices we are sampling
* Move locking to be per-actmon-device

The ACTMON block can monitor several counters, providing averaging and firing
interrupts based on watermarking configuration. This implementation monitors
the MCALL and MCCPU counters to choose an appropriate frequency for the
external memory clock.

This patch is based on work by Alex Frid <afrid@nvidia.com> and Mikko
Perttunen <mikko.perttunen@kapsi.fi>.
