There have been many reports recently about broken HID devices, the
diagnosis of which required users to recompile their kernels in order
to be able to provide debugging output needed for coding a quirk for
a particular device.

This patch makes CONFIG_HID_DEBUG default y if !EMBEDDED and makes it
possible to control debugging output produced by HID code by supplying
'debug=1' module parameter.

Every file should include the headers containing the prototypes for
it's global functions.

CONFIG_INPUT_DEBUG is non-existent option, so remove anything depending
on it.

Also, as we have new CONFIG_HID_DEBUG, this should be used on places
where ifdef DEBUG was used before.

hid-debug.h contains a lot of code, and should not therefore
be a header.

This patch moves the code to generic hid layer as .c source, and
introduces CONFIG_HID_DEBUG to conditionally compile it, instead
of playing with #define DEBUG and including hid-debug.h.
