[media] media: exynos4-is: add flags to dummy Exynos IS i2c adapter

Add simple 'functionality' member to dummy Exynos IS i2c adapter to make
i2c core happy and get rid of NULL pointer dereference during Exynos4 IS
probe since v4.10-rc1:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000
