dt-bindings: tpm: Document Microsoft fTPM bindings
A driver for Microsoft's firmware-based Trusted Platform Module (fTPM)
was merged with commit 09e574831b27 ("tpm/tpm_ftpm_tee: A driver for
firmware TPM running inside TEE"), but its devicetree bindings were not.
This is the only remaining undocumented compatible string for a TPM,
so add a DT schema based on the patch linked below.

dt-bindings: tpm: Convert IBM vTPM bindings to DT schema
Convert the devicetree bindings for the IBM Virtual Trusted Platform
Module to DT schema. Drop properties which are already documented in
tpm-common.yaml.
Document the "IBM,vtpm20" compatible string introduced by commit
18b3670d79ae ("tpm: ibmvtpm: Add support for TPM2").

dt-bindings: tpm: Convert Google Cr50 bindings to DT schema
Convert the devicetree bindings for the Google Security Chip H1 running
Cr50 firmware to DT schema.
The chip can be attached to SPI or I²C. Existing devicetrees use the
same "google,cr50" compatible string for both cases without additionally
specifying a generic "tcg,tpm_tis-spi" or "tcg,tpm-tis-i2c" compatible.
The chip therefore cannot be documented in the tcg,tpm_tis-spi.yaml and
tcg,tpm-tis-i2c.yaml schemas: The validator would select both of them
and complain about SPI properties when the chip is an I²C peripheral.
So document the chip in a schema of its own which includes both, SPI and
I²C properties by reference.
