soc/intel/cannonlake: Plumb TetonGlacierMode into dt
The following plumbs through the enabling of Intel's TetonGlacierMode
allows for reconfiguring the PCIe lanes at runtime for hybrid drives
to be accessable via devicetree.
BUG=b:149171631
BRANCH=none
TEST=Swap between x4 NVMe drives and 2x2 Teton Glacier hybrid drives and
run lsblk, lspci, and nvme tools to confirm dynamic PCIe configuration
on Puff.
