hte: tegra-194: Use proper includes

The test driver uses the gpiod consumer API so include the right
<linux/gpio/consumer.h> header. This may cause a problem with
struct of_device_id being implcitly pulled in by the legacy
header <linux/gpio.h> so include <linux/mod_devicetable.h>
explicitly as well.

While at it, drop explicit moduleparam.h (it's included with module.h)
and sort the headers.
