Input: htcpen - switch to DMI-based autoloading

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

Having module device table based on PNP id produces the following warning:

CC drivers/input/touchscreen/htcpen.o
drivers/input/touchscreen/htcpen.c:50: warning: 'pnp_ids' defined but not used

This happens because it is not a PNP driver, bit rather ISA driver and
pnp_ids table is not used anywhere. To fix this issue let's switch to
DMI-based module table instead,
