Nicolas Boichat 7dc3066837 poppy: Enable pull-down on SPI flash MISO pin to avoid leakage

This enables pull-down on F_DIO1 (SPI MISO), and F_DIO0 (SPI MOSI),
whenever the EC is not doing SPI flash transactions. This avoids
floating SPI buffer input (MISO), which causes power leakage.

BRANCH=none
BUG=b:64797021
TEST=Flash soraka, check output of rw .b 0x400C3029 is 0x80
     Check that U58 (SN74LVC244ARWPR) leakage drops from 1.2 mA to 0.
TEST=1. flashrom from host to EC spi flash using servo
     2. flashrom from host to EC spi flash using suzyq
     3. flashrom from device to EC spi flash
     4. EC SW sync
