[PATCH v2 2/6] arm64: dts: exynos: gs101: fix usi8 default mode

[André Draszik]

While commit 6d44d1a1fb62 ("arm64: dts: exynos: gs101: define USI8 with
I2C configuration") states that the USI8 CONFIG is 0 at reset, the boot
loader has configured it by the time Linux runs and it has a different
value at this stage.

Since we want board DTS files to explicitly select the mode, we should
set it to none here so as to ensure things don't work by accident and
to make it clear that board DTS actually need to set the mode based on
the configuration.

Fixes: 6d44d1a1fb62 ("arm64: dts: exynos: gs101: define USI8 with I2C configuration")
