4.8 fixes + other misc fixes
Makefile: enable -O3
ARM: hw_breakpoint: enable HAVE_HW_BREAKPOINT feature flag

HAVE_HW_BREAKPOINT was disabled temporarily from commit
480a82f59712136b51ee5ca05c4f22c1738010c5. Issue not seen with the
latest kernel hence re-enable the feature and fix merge issue from
previous kernel upgrade.

ARM: hw_breakpoint: Clear breakpoints before enabling monitor mode
The reset value of the BCR, BVR, WCR, and WVR registers are all
UNKNOWN on ARMv7. Unfortunately, reset_ctrl_regs() clears these
registers *after* enabling monitor mode, not before, and so some
implementations may experience UNPREDICTABLE behavior if the
reset values of these registers are non-zero. Clear the
breakpoints before enabling monitor mode so that we don't
experience boot hangs/loops due to breakpoints being enabled
out of reset.

doubletap2wake (WIP) still testing
drivers: input: Port of doubletap & swipe for geeb from franco

port by xboxfanj & houst0nn
I also did some extra cleanup and squashed and fixed franco's addition
drivers: input: add a mechanism to wake the device by either double tapping the display or swipping from wherever you want. The device deep sleeps but the digitizer is still powered on, otherwise it couldn't detect touch events. Battery usage should be little to minimal, but I haven't ran any numbers.

drivers: input: major improvements on the doubletap to wake feature.
