Peter Seiderer 03ee513bda linux: fix fbtft kernel extension
Fixes fbtft kernel extension bug reported by Richard Fergusson ([1]):

drivers/video/Kconfig:2525: can't open file
"drivers/video/fbdev/fbtft/Kconfig"

Fix: write the right fbtft/KConfig path to video/Kconfig or
video/fbdev/Kconfig (instead of hard coded one)
