drivers: input: touch filter control enablement

1) Turn off accuracy filter by default and add a switch to turn it
on. Since it is off by default, users with issues should be fixed I
hope.  Good practice will be to turn off, set params, and turn on to
that the touchscreen is not disrupted if the user is interacting with
it.

To enable:
echo 1 > /sys/devices/virtual/input/lge_touch/accuracy_filter_enable

To disable:
echo 0 > /sys/devices/virtual/input/lge_touch/accuracy_filter_enable

2) Allow stock defaults to be set on init so when a user decides they
want to enable the filter, they will have reasonable defaults ready to
go.

3) TESTING ONLY - Allow Jitter filter control to be turned on in a
similar way and allow the adjust_margin parameter to be adjusted.  I
thought this might be useful for stylus control or users with big hands
etc, but after initial testing it doesn't seem to be useful at all and
makes the touch screen very hard to use. We will leave in for more
testing for now. Will likely pull unless it proves to be useful for some
purpose.

/sys/devices/virtual/input/lge_touch/jitter_filter_enable

Notes: The stock kernel already allows all these parameters to be set in
one command as below. These recent changes initiated by Franco opens
each component up so that apps/scripts can more easily read the
variables. Since we add the ability to read by component, it makes sense
to also allow write by component and makes it easier to understand what
variables are being adjusted.
