mb/prodrive/hermes: Fix PCIe ClkSrc configuration

Correct the PCIe clock source configuration as per the schematics.
Apparently, FSP does not turn off unused PCIe clock sources when using
SPS (Server Platform Services) firmware, but it does when using CSME
firmware.

TEST=BMC and Ethernet NICs get detected when using CSME firmware.
