Updated the Measured Boot PoC to be compliant with the current TF-A
implementation that supports multiple Measured Boot backends, which
are the RSS and Event Log.

This patch adds a new optional member `pwr_domain_validate_suspend` to
the `plat_psci_ops_t` structure that allows a platform to optionally
perform platform specific validations in OS-initiated mode. This is
conditionally compiled into the build depending on the value of the
`PSCI_OS_INIT_MODE` build option.
In https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17682,
the return type of the `pwr_domain_suspend` handler was updated from
`void` to `int` to allow a platform to optionally perform platform
specific validations in OS-initiated mode. However, when an error code
other than `PSCI_E_SUCCESS` is returned, the current exit path does not
undo the operations in `psci_suspend_to_pwrdown_start`, and as a result,
the system ends up in an unexpected state.
The fix in this patch prevents the need to undo the operations in
`psci_suspend_to_pwrdown_start`, by allowing the platform to first
perform any necessary platform specific validations before the PSCI
generic code proceeds to the point of no return where the CPU_SUSPEND
request is expected to complete successfully.

As per recent changes to OPTEE's fvp.mk file, both options
"MEASURED_BOOT" and "MEASURED_BOOT_FTPM" are required for the fTPM
application to be built.

Top level sections are not numbered. Adding numbers makes referring to
sections easier. For example the Maintainers page changes from
"about/3.1" to simply "1.3.1".

Add documentation to build and run a PoC based on the OP-TEE toolkit
to show how TF-A Measured Boot can interact with a third party (f)TPM
service.
