Dmitry Torokhov d95f0c4e5b Input: tsc2004/5 - fix handling of VIO power supply
The chip needs to be powered up before calling tsc200x_stop_scan() which
communicates with it; move the call to enable the regulator earlier in
tsc200x_probe().

At the same time switch to using devm_regulator_get_enable() to simplify
error handling. This also makes sure that regulator is not shut off too
early when unbinding the driver.
