Relying on CONFIG_PM_SLEEP to set PM ops is not necessary
since core will handle everything internally. One have to only make sure
that functions that can go unused are marked with __maybe_unused.

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

Check for attribute_group structures that are only stored in the
attrs filed of iio_info structure. As the attrs field of iio_info
structures is constant, so these attribute_group structures can also be
declared constant.
Done using coccinelle:

static struct attribute_group i@p = {...};

Previously most drivers that used a i2c_check_functionality() check
condition required various error codes on failure. This patchset
converts to a standard of -EOPNOTSUPP

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.
