mb/google/poppy/variants/nocturne: Disable pull-down of GPP_E9/E10
While these pins were set to a pull-down 20KOhm, NPCX EC consumes
~2.1mW higher power. Becasue there was leakage current on both GPIO67
and GPIO70 from NPCX EC. With the external pull-up 10KOhm for
USB_OC0#/USB2_OC1#, this wasn't enough to prevent leakage current.
BUG=b:117139495
TEST=Check nxpc EC power to see power improvement
