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.
