For Waipio onwards, mdp core clock rate needs to be requested
through the mmrm driver, which will make sure the requested
rate can be sustained by the its power rail, which is shared
by multiple clients.
Current change adds the support to request the mdp core clk rate
through mmrm driver as well as returns the corresponding failures
to user space during when a rate cannot be supported by the
system.
