msm: msm_bus: Change MDP port interleaved setting

When display driver requests bandwidth on MDP port 0, it was
automatically divided between port 0 and port 1 by the bus driver
as a part of interleaving. Since MDP port 1 was never used,
this did not have any impact.

Now, the display driver needs to use MDP port 1 such that MDP
ports should be able to use the bandwidth non-uniformally.
To enable these ports to use unequal amount of bandwidth,
it is required that bus driver does not divide bandwidth
between port 0 and port 1.
The display team is now responsible for requesting bandwidth
explicitly on both ports.
