To isolate CPUs (isolate from hrtimers) from sysfs using cpusets, we need some
support from the hrtimer core. i.e. A routine hrtimer_quiesce_cpu() which would
migrate away all the unpinned hrtimers, but shouldn't touch the pinned ones.
This patch creates this routine.

'Pinned' information would be required in migrate_hrtimers() now, as we can
migrate non-pinned timers away without a hotplug (i.e. with cpuset.quiesce). And
so we may need to identify pinned timers now, as we can't migrate them.
This patch reuses the timer->state variable for setting this flag as there were
enough number of free bits available in this variable. And there is no point
increasing size of this struct by adding another field.

CONFIG_CMA_DEBUG was #defining DEBUG, which has the side effect of
changing the behavior of pr_debug statements to always print into
the dmesg log, as opposed to printing only if they are enabled via
dynamic debug.
Log etiquette indicates that messages should only be printed for
error conditions.

Fix the "status stuck at on" warning when disabling
disp_cc_mdss_mdp_lut_clk. The enable bit for this clock doesn't actually
do anything and instead the enable signal is tied to the enable bit of
disp_cc_mdss_mdp_clk. Even though this clock isn't truly votable, use
BRANCH_HALT_VOTED to ensure that the client enables disp_cc_mdss_mdp_clk
before this one and that we don't throw a warning on the disable path
when the clock doesn't actually turn off yet.
