Furquan Shaikh 7340efcf19 mb/google/zork: Configure GPIO_40 as drive low in sleep path
This change configures GPIO_40 (NVME_AUX_RESET_L) as drive low in
sleep path so that the PERST# to NVMe device keeps asserted until
coreboot reconfigures it as high on S3 resume path. This is similar to
the earlier change for PCIE_RST1_L but helps platforms that use
NVME_AUX_RESET_L instead of PCIE_RST1_L. GPIO_40 lives in S5 domain,
hence it retains state across S3 entry/exit.
