Fixes V5 and V5X over current not being reported

[davids5]

As recommended in the BQ24315 datasheet V5 introduced a series 47K Ohm resistor in the FAULT line connection to the CPU on GPIO_VDD_5V_HIPOWER_OC and GPIO_VDD_5V_PERIPH_OC.

This PR remove the pullup in GPIO config for GPIO_VDD_5V_HIPOWER_OC and GPIO_VDD_5V_PERIPH_OC to correct VinL when /FAULT is true.
