The current check for XDCI enabled uses a static device path to an
internal PCI device at a very late point in the boot flow. At this
time the devicetree has been processed and disabled devices have been
already removed. If this device (00:15.1, XDCI) is disabled in
devicetree this will trigger the message
'BUG: check_xdci_enable requests hidden 00:15.1' in the log.
This looks weird and is wrong since it is not a bug to disable this
device when it is not needed.
To avoid this look up the devicetree by a tree walk instead of using
a static value for the devicetree.

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.

As per MP service specification, EDK2 is allowed to specify the mode
in which a 'func' routine should be executed on APs.
`SingleThread` sets to 'true' meaning to execute the function one by
one (serially) or sets to 'false' meaning to execute the function
simultaneously.
MP service API `StartupAllAPs` was designed to pass such options as
part of function argument.
But another MP service API `StartupAllCPUs` doesn't specify any such
requirement. Running the `func` simultaneously on APs results in
a coherency issue (hang while executing `func`) due to lack of
acquiring a spin lock while accessing common data structure in
multiprocessor environment.
