platform/x86: dell-wmi: add new dmi mapping for keycode 0xffff
This keycode is used by Dell as a no-op for keys that should have
no function.
This keycode is never triggered by a keypress in practice, rather
it is included from the 0xB2 DMI table at startup.
This prevents the following messages from being logged at startup on a
Dell Inspiron 5593:
dell_wmi: firmware scancode 0x48 maps to unrecognized keycode 0xffff
dell_wmi: firmware scancode 0x50 maps to unrecognized keycode 0xffff
as per this code comment:
Log if we find an entry in the DMI table that we don't
understand. If this happens, we should figure out what
the entry means and add it to bios_to_linux_keycode.
