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").

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.

<title>dt-bindings: tpm: Consolidate TCG TIS bindings</title>

A significant number of Trusted Platform Modules conform to the "TIS"
specification published by the Trusted Computing Group ("TCG PC Client
Specific TPM Interface Specification").  These chips typically use an
SPI, I²C or LPC bus as transport (via MMIO in the latter case).  Some
of them even support multiple of those buses (selectable through a
config strap) or the same chip is available in multiple SKUs, each with
a different bus interface.

The devicetree bindings for these TPMs have not been converted to DT
schema yet and are spread out across 3 generic files and 2 chip-specific
files.  A few TPM compatible strings were added to trivial-devices.yaml
even though additional properties are documented in the plaintext
bindings.

Consolidate the devicetree bindings into 3 yaml files, one per bus.

Move common properties to a separate tpm-common.yaml.

Document compatible strings which are supported by the TPM TIS driver
but were neglected to be added to the devicetree bindings.

Document the memory-region property recently introduced by commit
1e2714bb83fc ("tpm: Add reserved memory event log").
