sunxi: video: Fix VIDEO_LCD_PANEL_I2C being enabled by default

Fix a typo in board/sunxi/Kconfig which caused VIDEO_LCD_PANEL_I2C to be
enabled on all sunxi boards. Also fix a compile error which shows up once
VIDEO_LCD_PANEL_I2C is actually disabled on most boards as it should be.

 	Say y here if the LCD panel needs to be configured via i2c. This
 	will add a bitbang i2c controller using gpios to talk to the LCD.
