soc/intel/alderlake: Add ACPI addition for USB4/TBT latency optimization
The PCI-SIG engineering change requirement provides the ACPI additions
for firmware latency optimization. This change adds additional ACPI DSM
function with both of FW_RESET_TIME and FW_D3HOT_TO_D0_TIME to the
USB4/TBT topology which has the same implementation on Tiger Lake in
commit I5a19118b75ed0a78b7436f2f90295c03928300d7.
BUG=b:199757442
TEST= It was validated that the first connected device waits only 50ms
instead of 100ms and all functions work on Alder Lake platform boards.
