ARM: dts: msm: List all possible BW levels in cpubw for 8974

With the cpubw_hwmon devfreq governor available in Krait based CPUs, it's
important to list all the possible BW levels to get all the benefit from
the cpubw_hwmon governor. Also fix the use of a non-existent BW level in
msm-cpufreq device.

msm: kgsl: Fix range checking for profile wrapping

There is a chance that the profile code will not wrap correctly.
This can cause the in stream profiling to cause buffer pre-run
or undershoot (accessing data before the buffer). Fix logic to
cause the correct wrapping.

msm: kgsl: Don't open kgsl device in erroneous case

If kgsl_get_process_private() returns NULL, it goes to
err_stop with result = -ENOMEM. If open_count is 0,
adreno_stop() overwrites the result variable with 0.
This leads to kgsl_open() to be successful while it
shouldn't.
