soc/intel/cannonlake: Add PcieRpHotPlug config to FSP-M

Commit b67c5ed [3rdparty/fsp: Update submodule pointer to newest master]
updated the FSP binaries/headers for Comet Lake, which included a change
moving PcieRpHotPlug from FSP-S to FSP-M. Unfortunately the existing
UDP in FSP-S was left in and deprecated, which allowed the change to go
unnoticed until it was discovered that hotplug wasn't working.

Since other related platforms (WHL, CFL) share the SoC code but use
different FSP packages, add the setting of the PcieRpHotPlug UPD to
romstage/FSP-M and guard it with '#if CONFIG(SOC_INTEL_COMETLAKE)'.

Test: build/boot Purism Librem 14, verify WiFi killswitch operates
as expected / WiFi is re-enabled when turning switch to on position.
