mainboard/facebook/watson: add variant watson_v2

Watson V2 is the 2nd board variant based on Watson baseboard.

One aspect of the difference between watson V2 and watson (V1) is:
* Watson V2 has TPM2 chip instead of TPM1 chip.
* Watson V2 needs to have measured boot enabled.

TESTED=Made Watson V2 image, checked boot log and verfied that TPM2
is detected by both coreboot and target OS, that coreboot is measured.

TPM: Measured FMAP: COREBOOT CBFS: bootblock into PCR 2
TPM: Measured FMAP: COREBOOT CBFS: fallback/romstage into PCR 2
TPM: Measured FMAP: COREBOOT CBFS: fallback/ramstage into PCR 2
TPM: Measured FMAP: COREBOOT CBFS: cpu_microcode_blob.bin into PCR 2
TPM: Measured FMAP: COREBOOT CBFS: fallback/dsdt.aml into PCR 2
TPM: Measured FMAP: COREBOOT CBFS: fallback/payload into PCR 2
