[U-Boot] [PATCH 08/18] exynos5: config: prepare for dm i2c support

Hi Przemyslaw,

>So this commit allows for test ported driver before switch
>the Exynos5 boards to DM I2C at all.

Quick test over SMDK 5250 after replacing #if 0 -> 1.
Looks like there is some problem in changing bus beyond 7.
Please check.

Console prints are as follows -

SMDK5250 # i2c dev 8
Setting bus to 8
Failure changing bus number (-19)
exit not allowed from main input shell.
