soc/intel/tigerlake: Add Hot-Plug and PME event handlers for Thunderbolt
This change adds Hot-Plug and power management event handers(_L61 & _L69) respectively for Thunderbolt in the GPE scope. The _L61 method invokes sub-method HPEV to support Hot-Plug wake event from Thunderbolt PCIe root ports. This method intercepts Presence Detect Changed interrupt and make sure the L0s is disabled on empty slots prior booting to OS. The _L69 method checks and clears root port's PME SCI status.
BUG=b:156435065 TEST=Verified multiple hot plug successfully with Lenovo dock.
