HACK: Enable PCIe refclk 100M alone

Don't pull into TOT. Thanks.  b/170703028
This patch is just to open the refclk of pcie during the coreboot stage for PCIe hardware compliance testing. If Alvis wants to continue to test pcie hardware, please cherry-pick the patch.
Set GPIO65 pinmux for PCIe function which is clkreq#.
