soc/intel/alderlake/acpi: Changing USB ports indexing.
xhci.asl places the SS ports at 11-14, following HS ports 1-10. However,
for Nissa, the kernel detects 12 HS ports 1-12 and 4 SS ports at 13-16,
resulting in the PLD intended for SS ports 1 and 2 being associated with
HS ports 11 and 12.
Changing the asl for SS to 13-16 makes locations associate correctly and
peering work.
BUG=b:234544025
BRANCH=firmware-brya-14505.B
TEST=manually verified on Nissa and Brya devices
