Add the missing invocations of the MODULE_DESCRIPTION() macro.

Note: All HID drivers that had explicit entries in the MAINTAINERS
file were fixed individually. This patch fixes all remaining HID
drivers that fall under the generic "HID CORE LAYER" entry in the
MAINTAINERS file.  Almost all descriptions were taken from the header
comment in each file.

* There are several variants for 0419:0001:
*
* 1. 184 byte report descriptor
* Vendor specific report #4 has a size of 48 bit,
* and therefore is not accepted when inspecting the descriptors.
* As a workaround we reinterpret the report as:
* Variable type, count 6, size 8 bit, log. maximum 255
* The burden to reconstruct the data is moved into user space.
*
* 2. 203 byte report descriptor
* Report #4 has an array field with logical range 0..18 instead of 1..15.
*
* 3. 135 byte report descriptor
* Report #4 has an array field with logical range 0..17 instead of 1..14.
*
* 4. 171 byte report descriptor
* Report #3 has an array field with logical range 0..1 instead of 1..3.
