samsung-laptop: add a small debugfs interface
This allow to call arbitrary sabi commands wihout
modifying the driver at all. For example, setting
the keyboard backlight brightness to 5 using debugfs
interface can be done like that:
; Set the command
echo 0x78 > command
; Set the data
echo 0x0582 > d0
; Fill the rest with 0
echo 0 > d1
echo 0 > d2
echo 0 > d3
; And issue the command
cat call
