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
