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 Change-Id: I685d876461c263f07ca4c8f8046635cb7087279c Signed-off-by: Roy Mingi Park <roy.mingi.park@intel.com> Reviewed-on: https://review.coreboot.org/29007 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Pratikkumar V Prajapati <pratikkumar.v.prajapati@intel.com> Reviewed-by: Furquan Shaikh <furquan@google.com>
