Reading the load value may increase CPU power consumption
temprorarily. In most cases we are ok with a value that
was read a moment earlier.
This patch introduces a software shadow for gpu load. The shadow
is updated before starting scaling and all scaling code paths use
the sw shadow.

Currently creation of the load sysfs node is bound to devfreq
profile initialisation, however, this information is useful even
if the scaling is not enabled. This patch modifies the code to create
the sysfs node always.
