[POWERPC] adbhid: Enable KEY_FN key reporting
When a Fn key is used in combination with another key in ADB keyboards it will generate a Fn event and then a second event that can be a different key than pressed (Fn + F1 for instance can generate Fn + brightness down if it's configured like that). This enables the reporting of the Fn key to the input system. As Fn is a dead key for most purposes, it's useful to report it so applications can make use of it. One example is apple_mouse (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the second and third keys using a combination of keyboard keys and the mouse button. Other applications may use the KEY_FN as a modifier as well. I've been updating and using this patch for months without problems.
