The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is likely another ITE based design. The controller die is directly bonded to the PCB with a blob of black glue on top so there are no markings and the 258a vendor-id used is unknown anywhere. But the keyboard has the exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard I have *and* it has the same quirky behavior wrt the rfkill hotkey. Either way as said this keyboard has the same quirk for its rfkill / airplane mode hotkey as the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard.
