soc/intel/alderlake/acpi: Add Kconfig options for SCM and FCM
Software Connection Manager doesn't work with Linux 5.13 or later,
resulting in TBT ports timing out. Not advertising this results
in Firmware Connection Manager being used and TBT works
correctly.
Add Kconfig options to chose between SCM (Software Connection
Manager) and FCM (Firmware Connection Manager). FCM is primary, as
it's more compatible save for ChromeOS devices as ChromeOS uses
SCM.
Linux patch:
torvalds/linux@c6da62a
c6da62a219d028de10f2e22e93a34c7ee2b88d03
Tested with StarBook Mk VI (i7-1260P).
