[beta] touchscreen: add doubletap2wake for codina

this is a very simple and probably broken implementation of doubletap2wake. it senses for a touch and if two touches are not more than 500ms apart, the screen turns on. needs more extensive testing

touchscreen: allow press timeout to be tunable

also changed all sweep2wake vars to unsigned just in case

bln: allow configuration of blink delay

finally, we start customising bln

Change-Id: Ibe89372174051ef79154c57c020efa76581d2864
bln: allow separate configuration of blink on and off delays

also minor optimisation of bln_blink_mode check

devicesettings: need the appropriate modifications

dt2w: decrease press timeout by 1/2
500ms timeout is pretty long, decrease to near instantaneous humane taps

-O3 optimization
AIO: Don't plug the I/O queue in do_io_submit() Asynchronous I/O latency to a solid-state disk greatly increased between the 2.6.32 and 3.0 kernels. By removing the plug from do_io_submit(), we observed a 34% improvement in the I/O latency.

Unfortunately, at this level, we don't know if the request is to
a rotating disk or not.

lib/checksum.c: optimize do_csum a bit

Reduce the number of variables modified by the loop in do_csum() by 1,
which seems like a good idea.  On Nios II (a RISC CPU with 3-operand
instruction set) it reduces the loop from 7 to 6 instructions, including
the conditional branch.
