Subject: [PATCH v1 1/1] HID: debug: Remove duplicates from 'keys'

Duplicates in 'keys prevents kernel builds with clang, `make W=1` and
CONFIG_WERROR=y, for example:

drivers/hid/hid-debug.c:3443:18: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
 3443 |         [KEY_HANGEUL] = "HanGeul",              [KEY_HANGUP_PHONE] = "HangUpPhone",
      |                         ^~~~~~~~~
drivers/hid/hid-debug.c:3217:18: note: previous initialization is here
 3217 |         [KEY_HANGUEL] = "Hangeul",              [KEY_HANJA] = "Hanja",
      |                         ^~~~~~~~~

Fix this by removing them.

The logic of removal is that, remove...
1) if there is a constant that uses another defined constant, OR
2) the one that appears later in the list.
