Some of targets doesn't need MMRM but need binary compatibility
with targets which support MMRM.
A new api is added to support such scenarios & to ensure that
MMRM is disabled & MM clients can fall back to clk api.

While adjusting the voltage corner for all clients, number of
hw instances in not included. Also when calculating the old
current of a client number of hw blocks is not included.
Fixed the calculations to project the correct current calculation
when either overall voltage corner is adjested or corner is adjusted
for a client.

As voltage corners are shared among the clients
ranging from low to high priority. In order to
accomodate power requirement of high priority clients,
MMRM driver may throttle a client which is lower priority.
Added logic to bookkeep these clients and try to
reinstate them at later point of time.
