ARM: dts: LogicPD SOM-LV: Fix I2C1 pinmux 

The pinmuxing was missing for I2C1 which was causing intermittent issues
with the PMIC which is connected to I2C1.  The bootloader did not quite
configure the I2C1 either, so when running at 2.6MHz, it was generating
errors at times.

This correctly sets the I2C1 pinmuxing so it can operate at 2.6MHz

Fixes: ab8dd3aed0 ("ARM: DTS: Add minimal Support for Logic PD DM3730
SOM-LV")
