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>

The PM methods are basically the same for SPI and I2C busses, so let's
use the same dev_pm_ops for both of them.

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.

There is a move to deprecate bus-specific PM operations and move to
using dev_pm_ops instead in order to reduce the amount of boilerplate
code in buses and facilitate updates to the PM core. Do this move for
the ad7879 SPI driver.

The ad7879 driver is using the old bus method of only supporting one
at a time (I2C or SPI). So refactor it like the other input drivers
that support multiple busses simultaneously.
