platform/x86: thinkpad_acpi: add mapping for new hotkeys
The T470, X270 emits new hkey events in the 0x1311 - 0x1315 range. According to the user manual they should launch a user selected favorite application (star icon, 0x1311), snipping tool (0x1312, currently ignored), enable/disable bluetooth (0x1314) and open they keyboard settings (0x1315). The third nibble (0xf00) is used to differentiate between the original hotkeys, the adaptive keyboard codes and the new, additional ones.
