phyBOARD-i.MX8MP-Pollux.
RTC trickle-charger devicetree property is dependent on the
phyboard-pollux design.

Removes the pull-up resistor from the pad's settings to keep it
consistent for all boards. We have pull-ups in hardware on all boards so we
don't need to set the additional one from the iomux controller.
