cpuidle: Add last_residency trace event for residency profiling
omap4: cpuidle: Some obvious optimisations to the code path
omap44xx: cpuidle: Update target residencies to saner values

The current values are insane.

There is no possible way power saving
can be attained by heading into C4 for not much more than 1ms. The average
values are in the 20ms range, so why do we need to even entertain entering
at much lower values when we will use more power than we save in doing so.

The actual recommended values are shown in 79e796f7b993bd82ad108fa488c35ddd1b9387eb
but for some obscure reason, in 16385c726d55f9e84bbc60ff9e329a84d56a13a3 and
22e2193661b6bffcfdc1a4d17f6af0d1782ba860 they were updated to match the exit_latency.

This seems horribly wrong to me as there comes a point when the target residency is
so low that you use more power actually entering the state than you gain from the
insignificant amount of time you spend there.

With the values in this commit, C4 state is used for >95% of the time when the screen
is off, with C3 picking up the remainder.
During audio playback, C4 is used ~50% of the time, C3 is used ~25% of the time and C2
picks up whatever is left.
Update android binder to 3.3 version.
Update lowmemorykiller to 3.4 version.
ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problems

The idle status of the IP blocks and clocks inside the EMU clockdomain
isn't taken into account by the PRCM hardware when deciding whether
the clockdomain is idle.  Add a workaround flag in the clockdomain
code, CLKDM_MISSING_IDLE_REPORTING, to deal with this problem, and add
the code necessary to support it.

If CLKDM_MISSING_IDLE_REPORTING is set on a clockdomain, the
clockdomain will be forced active whenever an IP block inside that
clockdomain is in use, even if the clockdomain supports
hardware-supervised idle.  When the kernel indicates that the last
active IP block inside the clockdomain is no longer used, the
clockdomain will be forced idle, or, if that mode is not supported in
the hardware, it will be placed into hardware-supervised idle.

This patch is an equal collaboration with Jon Hunter
<jon-hunter@ti.com>.  Ming Lei <ming.lei@canonical.com>, Will Deacon
<will.deacon@arm.com>, Madhav Vij <mvij@ti.com>, Kevin Hilman
<khilman@ti.com>, Benoît Cousson <b-cousson@ti.com>, and Santosh
Shilimkar <santosh.shilimkar@ti.com> all made essential contributions
to the understanding of EMU clockdomain power management on OMAP.
