soc/intel/{common,alderlake}: Add missing ADL-N SKUs

Based on DOC #767454 (public) version 1.2. Allows to boot the
HARDKERNEL ODROID H4+ with N97 SoC. Without this patch the MCH ID
was not recognized and the SA driver did not pick up the stolen
ranges, causing the PCI MMIO allocation to be placed in the stolen
areas.

TEST=Boot HARDKERNEL ODROID H4+ with N97 SoC to Ubuntu 23.04.
