[PATCH] drivers/video: fix mb862xx_i2c depends issue build failure

[Paul Gortmaker]

Any randconfig that sets I2C=m and FB_MB862XX_I2C=y will
encounter a final link failure that looks like this:

drivers/built-in.o: In function `mb862xx_i2c_init':
drivers/video/mb862xx/mb862xx-i2c.c:165: undefined reference to `i2c_add_adapter'
drivers/built-in.o: In function `mb862xx_i2c_exit':
drivers/video/mb862xx/mb862xx-i2c.c:176: undefined reference to `i2c_del_adapter'

Since FB_MB862XX_I2C is a bool and not tristate, simply
don't offer it at all if core I2C support is not built in.
