tegra: Check for I2C support when using clock scaling
It is not possible to enable CONFIG_TEGRA_CLOCK_SCALING without I2C
and the current error message is not friendly. Add an explicit message
to the board file.
BUG=chromium-os:19004
TEST=build for Seaboard with and without I2C and see that it gives an
error in the second case but not the first
