[PATCH] [media] msp3400: use IS_ENABLED check instead of #if

[Arnd Bergmann]

A recent patch broke the msp3400 driver when CONFIG_MEDIA_CONTROLLER
is not set:

drivers/media/i2c/msp3400-driver.h:107:5: error: "CONFIG_MEDIA_CONTROLLER" is not defined [-Werror=undef]

It was clearly a typo, and this patch changes the
"#if CONFIG_MEDIA_CONTROLLER" to a working IS_ENABLED() check.
