msm: mdss: Add SMP parameters into hw capabilites

To handle use cases better, expose smp_mb_cnt and
smp_mb_per_pipe to userspace as part of hardware capability.
Pipes availablity for a use case can be computed taking these
values, based on which, composition decisions can be made.

msm: mdss: Add backlight attenuation mechanism in AD auto strength mode

AD backlight attenuation provides the ability to modulate backlight based
on calibration before feeding it to AD core for strength computation.

cpufreq: Fix broken uevents for cpufreq governor and cpu devices

cyanogens uevent commit when the governor changes was rendered
non-working since kitkat (or so) as the uevent filter function
caused events to be dropped. Now hook into cpufreq_core_init()
and cpufreq_add_dev_interface() to create our basic ksets for
cpufreq and cpu devices. Also, we don't need to set environmental
data, so clean it up a bit.

This commit requires a change in ueventd.rc that add rules for
several files of interest.

genalloc: Correct nbytes calculation on long boundary

In existing code we calculate nbytes based on the byte
boundary, but genalloc uses bitmap for maintaining the
memory allocation aligned to long. So while calculating
nbytes we end up getting wrong nbytes.
example: lets say nbytes comes to 9 bytes for 70 bits when
bytes aligned,but if long aligned we will have 3 long words
i.e 12 bytes. This difference may lead to choosing the
wrong api for freeing the memory i.e Between kfree() and
vfree().
Fix was inspired by an upstream commit
eedce141cd2dad8d0cefc5468ef41898949a7031, bringing same fix
into the gen_pool_detroy path.

msm: lpm_levels: Fix incorrect computation of next wakeup time

The next event timer wakeup was incorrectly computed when the hard timer
event doesn't exist. Fix by ensuring the next wakeup is computed only
when a timer event is valid

msm: mpm-of: fix for "cxo_lpm_clk is unbalanced" slowpath warning.

The variable xo_enabled needs protection. It might get called
simultaneously from suspend and mpm worker thread context.
Added a mutex to prevent this.

cpufreq: Sync on thread migration optimizations

When threads migrate between CPUs the destination CPU will temporarily
have a boosted frequency and the source CPU will have a residual higher
frequency even though the load could have just been reduced. To avoid
leaving CPUs at a high frequencies notify the source CPU after a thread
migration and make the interactive governor's timer reschedule
conditionally.
