The hid-led driver works fine under 4.8.0, however with the next
kernel from today I get this:

Fix this by using a kmalloc'ed buffer when calling hid_hw_raw_request.

Delcom uses the report id to submit command information. To be able to
use the hidled framework also for Delcom devices we have to remove the
report id from struct hidled_config.

This patch migrates the USB LED driver to the HID subsystem.
Supported are Dream Cheeky Webmail Notifier / Friends Alert
and Riso Kagaku Webmail Notifier.
Benefits:
- Avoid using USB low-level calls and use the HID subsystem instead
(as this device provides a USB HID interface)
- Use standard LED subsystem instead of proprietary sysfs entries,
this allows e.g. to use the device with features like triggers
Successfully tested with a Dream Cheeky Webmail Notifier and a
Riso Kagaku Webmail Notifier compatible device.
