mb/prodrive/hermes: Map PCIe clocks to root ports

Map each PCIe clock source to the corresponding root port. Also, correct
the CLKREQ# mapping for clock sources not associated to any CLKREQ# pin.
The default `PcieClkSrcClkReq` value of 0 corresponds to CLKREQ# 0.

TEST=Check that Linux sees the same PCIe devices with this commit:

 - All 5 onboard Ethernet NICs
 - BMC
 - Two random graphics cards in PEG0 and PEG1 slots
 - M.2 M NVMe SSD
