ARM: dts: msm: lower LDO 11 minimum voltage constraint for msm8974

Change the minimum voltage constraint of PM8941 LDO 11 from 1.3 V
to 1.225 V.  This allows the RPM to reduce the voltage of LDO 11
when no consumers on the application processor require it to be
at the maximum level of 1.3 V.  This is particularly important
when a consumer on another processor needs LDO 11 to be enabled
but no consumer on the application processor requires the same.

Make the same change for PMA8084 LDO 11 on msm8974pro boards.

ion: system_heap: only use low gfp flags for order-0 pages

By trying a little harder to get high-order pages (by virtue of the
liberal gfp flags used for high-order allocations) we can actually
optimize performance since high-order pages seem to help a lot. Only use
the low-order flags as a last resort, when trying to allocate an order-0
page.

msm: mdss: optimize MDP pipes cleanup

There are cases where pipe cleanup can happen without display commit.
This means that the pipe was never programmed to hardware, in these
cases the pipe can be cleaned up without the need of display commit
cycle to happen. Also there is no need to access hardware to release
resources such as SMPs since they have not been programmed yet.

msm: lpm_levels: return new idle level to cpuidle framework

Need to return the new idle level to cpuidle framework
but just returned input value argument 'index' which is
not used actually at lpm_cpu_power_select().

msm: mdss: implement overlay prepare ioctl

Overlay prepare will allow a full frame with multiple overlays to be
configured at once and perform frame level checks before being pushed to
display. This function guarantees that if the call is successful, the
frame can be displayed successfully on the screen when display commit is
called.

PM / devfreq: Fix out of bounds access of transition table array

The previous_freq value for a device could be an invalid frequency that
results in a error value being returned from devfreq_get_freq_level().
Check for an error value before using that to index into the transition
table.

Not doing this check will result in memory corruption when previous_freq is
not a valid frequency.
