The I2C and SPI PM callbacks were identical (though wrapped in some
bouncing out to the bus specific container of the struct device and
then back again to get the drvdata). As such rather than just moving
these to SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() take the opportunity
to unify the struct dev_pm_ops and use the new EXPORT_SIMPLE_DEV_PM_OPS()
macro so that we can drop the unused suspend and resume callbacks as well
as the structure if !CONFIG_PM_SLEEP without needing to mark the callbacks
__maybe_unused.

An spi_driver does not need to set an owner, it will be populated by the
driver core.

Use __maybe_unused instead of ifdef guards around suspend/resume
functions, in order to increase build coverage and fix build warnings.

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

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 adxl34x SPI driver has what appears to be a typo referring to the
device as adx134x with the numeral 1 rather than letter l. This appears
to be an error so convert.

There is a general move to convert drivers to use dev_pm_ops rather than
bus specific ones in order to facilitate core development. Do this
conversion for adxl34x-spi.

Suspending and resuming the device should be separate from enabling
and disabling it through sysfs attribute and thus should not alter
ac->disabled flag.
