video: fbdev: pxa168fb: make pxa168fb_init_mode() return void 

No other functions use the return value of pxa168fb_init_mode() and the
return value is always 0 now. Make it return void. This fixes the
following coccicheck warning:

drivers/video/fbdev/pxa168fb.c:565:5-8: Unneeded variable: "ret". Return
"0" on line 597
