[coreboot] non-posted/posted MMIO on MMCONFIG

I check AMD BKDG and MMCONFIG region should be marked non-posted (CPU waits for 
transaction to complete). Also this suggest the PCI ENC. I think the early bar3 
code sets non-posted in sb700/rs780 but in general we dont have any generic support.


It looks we have no support for posted/non-posted MMIO resource type right?

As the side note, the fam10h has MMIO MMCONFIG region too.

Most likely we should for AMDadd the NON_POSTED resource and set the bit in 
resourcemap (the MMIO routing registers)
