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.

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

hte: handle nvidia,gpio-controller property
The dt binding adds nvidia,gpio-controller property from Tegra234 SoC
onwards to simplify code handling gpio chip search. The gpio chip search
is needed for the AON GPIO GTE instances to map the hardware timestamp
GPIO request (coming from the GPIO framework) to the tegra HTE
providers. The patch also adds new gpio chip match function to match
from the fwnode instead of the gpio controller label. The addition
of the property does not break ABI for the existing Tegra194 code.

hte: Fix possible use-after-free in tegra_hte_test_remove()
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.

Tegra194 device has multiple HTE instances also known as GTE (Generic
Hardware Timestamping Engine) which can timestamp subset of SoC lines
and signals. This provider driver focuses on IRQ and GPIO lines and
exposes timestamping ability on those lines to the consumers through
HTE subsystem.
Also, with this patch, added:
- documentation about this provider and its capabilities at
Documentation/hte.
- Compilation support in Makefile and Kconfig
