acpigen_ps2_keybd: Add Fn key to linux,keymap
Some devices may generate scancodes for the Fn key if they have one.
If they do, we should add them to the linux,keymap binding.
BUG=b:333096023
TEST=Flash DUT that emits a scancode for the Fn key, verify that it is
mapped to KEY_FN in the Linux kernel using `evtest` when pressing the Fn
key.
