add doubletap2wake, completely rewritten on the s2w template

This is as easy to port as s2w, if not easier since no touchscreen
coords are necessary for it to work.

Just throw it in your tree, force the touchscreen to stay online and
you are done.

[PATCH] mdss_dsi: do not power down panel when sweep2wake is enabled
 In order to detect touches during suspend, the panel must
 be powered on. When sweep2wake is enabled, change one of the
 panel-off-cmds in mdss_dsi_panel.c from 0x10 to 0x11.

mdss_dsi_panel: keep the panel gpio active and don't trigger a reset

This way we will suffer minimum leakage when sweep2wake is being used.
All that is kept online here is the chip controlling the panel and touch panel.
That chip is probably some pmic but either way, keeping it online will cause
minimum leakage. This is an improvement upon the original patch by flar2 which
led to massive leakage from the display regulators since all were kept online.

sweep2wake: massive update, bring on par with s2w2 except algorithm

This patches sweep2wake on par with s2w2, minus the detection algorithm.
Changes in detail:
- Remove dependency on a power key setter, use a dummy device.
- Remove dependency on a touchscreen driver, use an input callback
- Remove dependency on external sysfs functions
- Remove dependency on external reset calls
- Migrate all of this into sweep2wake

Porting to new devices is now easier than ever:
1. Define your device parameters in the Sweep2wake tuneables
2. Check if the android_touch_kobj is already used by your touchscreen driver
2a. If it is export it and define S2W_ANDROID_TOUCH_DECLARED
(This will prevent s2w from spawning it's own kobj)
3. Force the touchscreen driver to deliver signals in suspend and you are done.

sweep2wake: we no longer need irq_wake. remove it.
Also clean up variable declariation to save some space
