A new public function, rpres_get_max_freq, is added to perform a
lookup for the maximum supported frequency from the OPP table for
a remote processor device.
This API can be used by the remote resource layer in sharing this
data to the remote processor application code for performing power
related policy decisions.

Some devices like:
- iva
- dsp
- fdif
are being created for pm purposes and create them again
is not recommended. For these devices the pm framework is
exporting api's to get them.
If a resource is already created use the api to get the
device and add the platform data and information needed
for rpres to control such device.

Adding PM constraints to rpres driver:
- scale_dev: request a change in the opp of the
device or the domain the device is part of.
- set_lat: request a latency constraint on the
device or the domain the device is part of.
- set_bw: set the minimum bus troughput for this
device.

This new module create devices for resources than can be access
by the moteprocessor in omap4.
Note: sl2if has follow this sequence:
- sl2if
* A sequence is need to request them:
> iva_hd
> iva_seq0
> iva_seq1
> sl2if
* A sequence is need to release them:
> iva_seq1
> iva_seq0
> sl2if
> iva_hd
* Otherwise the PM transitions behavior is
abnormal
