mb/google/poppy/variant/nocturne: update GPIO configuration 

GPP_C19 is not being set as the code is incorrectly setting
GPP_C16 instead, causing SAR sensor not to work, so this change
sets GPP_C19 to NF1.

GPP_E3 is not being initialized in the code.  Initialize GPP_E3
to a no connect as documented in the board schematic.

BUG=b:117124878
TEST: 'emerge-coreboot chromeos-bootimage', flash nocturne and
verify that i2c transactions work for the left SAR sensor.
