These fields are rarely updated by L1 QEMU/KVM, sync them when L1 is trying to
read/write them and after they're changed. If CET guest entry-load bit is not
set by L1 guest, migrate them to L2 manaully.
Opportunistically remove one blank line in previous patch.

Adding a quirk flag "quirk_detect_quiet_flag" to program the minimum time
that LTSSM waits on entering Detect.Quiet state.

Torrent PHY PLL0 or PLL1 is used for DP depending on the single link or
multilink protocol configuration for which PHY is configured. In multilink
configurations with other protocols, either PLL0 or PLL1 will be used
for DP. For single link DP, both PLLs need to be configured at POR.

It makes sense to start with a simple node tiering model like this

I do want to mention a likely usage scenario that motivates the need
for a list of nodes as the demotion target of a source node.
Access to a cross-socket DRAM node is still fast enough. So to mini
