touch: Add the capability to simulate HW failure
Usage:
$> setprop vendor.touch.gti0.ical.override.result RESULT
The designate RESULT to be used for the designate CMD.
If no RESULT assign, the default value will be "0 - -2147483648".
$> setprop vendor.touch.gti0.ical.override.cmd CMD
The result of designate CMD(e.g. 202 or 301) to be overrode by the
designate RESULT. If the CMD is "xxx", the result of any CMD will
be overode with the designate RESULT.
