Some exynos boards require special handling of nRESET_OUT line for eMMC
memory to perform complete reboot e.g. Odroid X2/U3/XU3 boards.
This will support eMMC reset using DT from reset_misc of samsung common
board file.

This patch enables CONFIG_DM_I2C and also CONFIG_DM_I2C_COMPAT.
The last one should be removed when the dm pmic framework will
be finished.

The USB host code was missing gpio_request() calls before using the gpio
functions, causing errors to be printed out.
As a side note calls to max77686_set_buck_mode(OPMODE_OFF/OPMODE_ON) have
been removed, as they did not have any effect. This is as per Przemyslaw:
I looked into the documentation and there is a "ENB8" pin in PMIC package.
This pin allows steering BUCK8 ON/OFF by the hardware. If ENB8 is set to low
then you can do on/off. If high, then you cannot change its state by I2C
write, which seems to be the case with the Odroids.

Setting gpio value before dm gpio init has no effect,
so now, odroid gpio settings are moved after the gpio uclass init.
Using non-requested gpio pin cases printing error messages.
To avoid this, gpio_request() is added for those gpios.
