mb/pcengines/apu2: do not pass enabled PCIe ClockPM to AGESA 

Certain PCIe endpoints cause an exception inside AmdInitMid when PCIe
ClockPM is enabled in AGESA PCIe initialization structures. Disable it
to allow platform to boot with such devices. coreboot driver enables
the ClockPM correctly on such devices anyway.
