Ken Chang a859aa3df5 nyan*: Set GEN2 I2C pads to open-drain mode 
The VDDIO to GEN2 I2C SCL/SDA pins is 1.8V and the external
pull-up voltage is 3.3V (the external 3.3V > I/O 1.8V) thus
the pinmux E_OD bit of these two pins needs to be set to
ensure GEN2 I2C pads work fine on 3.3V.

BRANCH=nyan
BUG=none
TEST=observed voltage drop from 3.3V to 2.36V on gen2 i2c
on blaze w/o this change. the waveform looks good on both
scl/sda pins w/ this change.
