HID: asus: Add support for T100 keyboard 



The keyboard dock used with the Asus Transformer T100 series, uses
the same vendor-defined 0xff31 usage-page as some other Asus
keyboards. But with a small twist, it has a small descriptor bug which
needs to be fixed up for things to work.

This commit adds the USB-ID for this keyboard to the hid-asus driver
and makes asus_report_fixup fix the descriptor issue, fixing
various special function keys on this keyboard not working.
