Sweek2wake mode now switchable through "/sys/kernel/sweep2wake/s2w_switch" while running Android system without rebooting.

Possible values are (unchanged) :

0 - sweep2wake disabled
1 - sweep2wake enabled with backlight
2 - sweep2wake enabled without backlight

Original configuration method via cmdline is still taken into account at boot.

NB: Default value now is 2, and anything above 2 will behave like 1.
