msm: camera: Enable pixel line buffer for ispif

Enable pixel line buffer for ispif to handle fast incoming
data. This provides cusion to dowmstream components such as vfe
and helps in preventing UB buffer overflows.

msm: camera: Disable software override for axi wm priority

Remove the software override for write master priority because
hardware assigns priority to write masters based on data rate.

msm: msm_bus: Fix the 64-bit division during interleaving

When interleaving flag is enabled, the bandwidth is divided
between ports. There was an error in the division as the
macro was not correctly updated with the right order of using
bandwidth and port number when 64-bit division function
was used by the bus driver.
Correcting this for fixing the token allocation issues
observed.

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.

msm_fb: display: balance bus bandwidth on mdp axi port0 and port1

mdp read and write clients are connected on both mdp port0 and port1,
however, the bus bandwidth request is made on only port0. This change
divides mdp bw requests to port0 and port1 based on pipe connections
to mdp ports.
ab - no scaling factor - port0 and port1 split
ib - scaling factor - port 0 and port1 split

the snapshot process after recovery is completed.

Don't consider active_cnt variable if not already in ACTIVE state.
The active count variable does not necessarily exactly indicate the
number of open handles to GPU for switching power state. Hence,
only wait for active count to reach zero before switching to SUSPEND
state if, the current state is ACTIVE.
