The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The value of 'ret' is zero when of_hte_req_count() fails to get number
of entitties to timestamp. And returning success(zero) on this failure
path is incorrect.

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.

The Tegra234 AON GPIO instance and LIC IRQ support HTE. For the GPIO
HTE support, it also requires to add mapping between GPIO and HTE
framework same as it was done with Tegra194 SoC.

del_timer() does not wait until the timer handler finishing.
This means that the timer handler may still be running after
the driver's remove function has finished, which would result
in a use-after-free.
Fix it by calling del_timer_sync(), which makes sure the timer
handler has finished.

The test driver uses IRQ and GPIO lines to timestamp using HTE
subsystem. The patch also adds compilation support in Kconfig and
