This also updates the devm_iio_device_alloc() call to consider the device object as the parent device by default. Having it passed like this, should ensure that any IIO device object already has a device object as parent, allowing for neater control, like passing the 'indio_dev' object for other stuff [like buffers/triggers/etc], and potentially creating iiom_xxx(indio_dev) functions. With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an update to pass the parent object as a parameter. In the next patch all devm_iio_device_alloc() calls will be handled.
