 driver Added entries to unsuported wmi codes in ideapad_keymap[] and one
 check in wmi_nofify in order to get wmi code 0x13d to trigger platform_profile_cycle

noted. About the performance button, under windows id does toggle the
performance mode, I would much rather have a assignable key, but will
bind it to platform_profile_cycle().
Thanks,
Gašper
