arm64: dts: ti: k3-j784s4: Fix I2C pinmux pull configuration

The I2C pins for some of the instances on J784S4/J742S2/AM69 are
configured as PIN_INPUT_PULLUP while these pins are open-drain type and
do not support internal pull-ups [0][1][2]. The pullup configuration
bits in the corresponding padconfig registers are reserved and any
writes to them have no effect and readback checks on those bits fail.

Update the pinmux settings to use PIN_INPUT instead of PIN_INPUT_PULLUP
to reflect the correct hardware behaviour.
