Some platforms need the pendown GPIO debounce time setting programmed.
Since the pendown GPIO is handled by the driver, the debounce time
should also be handled along with the pendown GPIO request.

This patch converts the drivers in drivers/input/* to use the
module_spi_driver() macro which makes the code smaller and a bit
simpler.

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};
// </smpl>

With commit 67d0a0754455f89ef3946946159d8ec9e45ce33a we mark strict_strtox
as obsolete. Convert all remaining such uses in drivers/input/.

Also change long to appropriate types, and return error conditions
from kstrtox separately, as Dmitry sugguests.

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in input dir
are actually calling out for <module.h> explicitly in advance.

Use gpio_request_one() instead of multiple gpiolib calls.
This also simplifies error handling a bit.

The pendown gpio was requested but not configured for input.
Configure it for input.

Just set vref_mv in your platform config to use external vref. Otherwise
the internal one is used.
