HID: sony: Make DS4 bt poll interval adjustable
By default when using bluetooth the DS4 reports data at about 1kHz, which is quite fast especially on weak devices. We now make the device use the USB poll interval, which is a fixed 4ms. In addition we make the value adjustable through sysfs. The error handling in sony_input_configured is a little tricky. It is not easy to add other goto's as not all codepaths have logic for adding this attribute. Luckily we are setting the value for the attribute to a default value, so we can use that to detect if we need to remove the file.
