Subject: tsc2007: Cancel work sync, increase polling frequency, make exit platform hw callback optional
In the remove function, ancel the work using the _sync version,
to make sure any running "work" is finished. Make the
exit_platform_hw callback optional since it's not needed on all
platforms.
When the screen is touched, the polling frequency is increased
to reduce the risk of missing taps.
