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. The _L69
method checks and clears root port's PME SCI status.
BUG=b:156435065
TEST=Verified multiple hot plug successfully with Lenovo dock.
