mb/google/poppy/variants/nautilus: Update camera power enable GPIOs
This change updates the camera power enable GPIOs as per the latest
schematics. With this update, since one of the enable GPIOs is using a
UART0 pin, set UART0 to PchSerialIoSkipInit in devicetree so that
FSP-S does not re-configure the UART0 GPIOs.
