Input: amikbd - allocate temporary keymap buffer on the stack

Browse source 
Allocate the temporary buffer needed for initialization of the console
keyboard maps (512 bytes, as NR_KEYS = 256) on the stack instead of
statically, to reduce kernel size.

add/remove: 0/1 grow/shrink: 0/0 up/down: 0/-512 (-512)
function                                     old     new   delta
temp_map                                     512       -    -512
