Fixes gcc '-Wunused-but-set-variable' warning:

drivers/video/fbdev/intelfb/intelfb_i2c.c: In function 'intelfb_gpio_setscl':
drivers/video/fbdev/intelfb/intelfb_i2c.c:58:6: warning:
 variable ‘val’ set but not used [-Wunused-but-set-variable]
drivers/video/fbdev/intelfb/intelfb_i2c.c: In function 'intelfb_gpio_setsda':
drivers/video/fbdev/intelfb/intelfb_i2c.c:69:6: warning:
